“Every new beginning comes from some other beginning’s end.”
– Seneca
The fediverse is a set of federated servers, typically using a communication protocol called ActivityPub which was devised by the social working group within the World Wide Web Consortium (W3C). At present it is mostly used for microblogging, although ActivityPub is sufficiently general that it can also be used for a variety of other purposes.
The word fediverse (federated universe) appears to have originated around 2012 as the first identi.ca website was ending and the pump.io project was beginning. The ActivityPub protocol was initially called ActivityPump, due to the influence which pump.io had upon its creation. Fediverse servers are typically referred to as “instances”.
Servers such as Mastodon are well known, but these are aimed at large scale deployments on powerful hardware running within data centers, making use of content distribution networks (CDN) and due to their large number of dependencies requiring someone with a high level of systems administration skill to maintain. Epicyon is designed for the opposite situation where it is only intended to have a single user or a small number of users (less than ten) running from your home location or on a modest VPS and where maintenance is extremely trivial such that it’s possible to keep an instance running for long durations with minimal intervention.
Epicyon is part of the small web category of internet software, in that it is intended to scale via federation rather than to scale vertically via resource intensive and expensive hardware. Think many small communicating nodes rather than a small number of large servers. Also, in spite of the prevailing great obsession with scale, not everything needs to. You can federate with a small number of servers for a particular purpose - such as running a club or hackspace - and that’s ok.
It is hardly possible to visit many sites on the web without your browser loading and running a large amount of javascript. Epicyon takes a minimalist approach where its web interface only uses HTML and CSS. You can disable javascript, or use a browser which doesn’t have javascript capability, and the user experience is unchanged. Lack of javascript also rules out a large area of potential attack surface.
Another common concern is being able to keep instances running. Instance abandonment creates a lot of disruption, and it’s often related to the amount of effort that it takes to keep things going. To avoid the maintenance burden becoming prohibitive, Epicyon is implemented in a simple manner with very few dependencies and no database. All data is just files in a directory, and upgrades are also straightforward. This degree of simplicity runs counter to the current trend within the software industry towards complex frameworks and large scale databases with elaborate and rapidly evolving dependencies.
Epicyon also includes some lightweight organizing features, such as calendar, events and sharing economy features.
You will need python version 3.7 or later.
On a Debian based system:
sudo apt install -y tor python3-socks imagemagick python3-setuptools python3-cryptography python3-dateutil python3-idna python3-requests python3-flake8 python3-django-timezone-field python3-pyqrcode python3-png python3-bandit libimage-exiftool-perl certbot nginx wgetThe following instructions install Epicyon to the /opt directory. It’s not essential that it be installed there, and it could be in any other preferred directory.
Clone the repo, or if you downloaded the tarball then extract it into the /opt directory.
cd /opt
git clone https://gitlab.com/bashrc2/epicyonCreate a user for the server to run as:
sudo su
adduser --system --home=/opt/epicyon --group epicyon
chown -R epicyon:epicyon /opt/epicyonThe content for RSS feed links can be downloaded and mirrored, so that even if the original sources go offline the content remains readable. Link the RSS/newswire mirrors with.
mkdir /var/www/YOUR_DOMAIN
mkdir -p /opt/epicyon/accounts/newsmirror
ln -s /opt/epicyon/accounts/newsmirror /var/www/YOUR_DOMAIN/newsmirrorTypically the server will run from a systemd daemon. It can be set up as follows:

}Enable the site:
ln -s /etc/nginx/sites-available/YOUR_DOMAIN /etc/nginx/sites-enabled/Forward port 443 from your internet router to your server. If you have dynamic DNS make sure its configured.
systemctl stop nginx
certbot certonly -n --server https://acme-v02.api.letsencrypt.org/directory --standalone -d YOUR_DOMAIN --renew-by-default --agree-tos --email YOUR_EMAIL
systemctl start nginxsystemctl restart nginxIf you need to use fail2ban then failed login attempts can be found in accounts/loginfailures.log.
If you are using the Caddy web server then see caddy.example.conf.
Now you can navigate to your domain and register an account. The first account becomes the administrator.
Since Epicyon does not use javascript there are no notifications in the browser. However, you can receive notifications via email, XMPP, Matrix or ntfy.
Copy the notifications script:
cp /opt/epicyon/scripts/epicyon-notification /usr/local/bin/epicyon-notification
chmod +x /usr/local/bin/epicyon-notificationIf you are using email for notifications and it is a single user instance then you might want to edit MY_EMAIL_ADDRESS within /usr/local/bin/epicyon-notification.
Then add the following to /etc/crontab.
# */1 * * * * root /usr/local/bin/epicyon-notificationIf you don’t have access to the clearnet, or prefer to avoid it, then it’s possible to run an Epicyon instance easily from your laptop. There are scripts within the deploy directory which can be used to install an instance on a Debian or Arch/Parabola operating system. With some modification of package names they could be also used with other distros.
Please be aware that such installations will not federate with ordinary fediverse instances on the clearnet, unless those instances have been specially modified to do so. But onion instances will federate with other onion instances and i2p instances with other i2p instances.
Unlike some other instance types, Epicyon is really easy to upgrade. It only requires a git pull to obtain the changes from the upstream repo, then set permissions and restart the daemon.
cd /opt/epicyon
git pull
chown -R epicyon:epicyon *
systemctl restart epicyonTo avoid running out of disk space you will want to clear down old inbox posts. Posts from your instance outboxes will be unaffected.
Create an archive script /usr/bin/epicyon-archive:
#!/bin/bash
cd /opt/epicyon || exit 0
/usr/bin/python3 epicyon.py --archive none --archiveweeks 4 --maxposts 32000You can adjust the maximum number of weeks and the maximum number of inbox posts as needed. Then add it as a cron entry.
echo "*/60 * * * * root /usr/bin/epicyon-archive" >> /etc/crontabYou will notice that within the systemd daemon the registration option is set to open. In a browser if you navigate to the URL of your instance then you should see a Register button. The first account to register becomes the administrator.
To avoid spam signups, or overloading the system, there is a maximum number of accounts for the instance which by default is set to 10.
Many social network systems have bad defaults, and that is for the purpose of maximizing the number of users and their level of engagement. Bad defaults usually create a combination of addiction patterns and involuntary oversharing and hence a viral network effect of escalating outrage and dependency. On small fediverse servers we can avoid having bad defaults, because there is no profit motive or drive for massive notoriety.
Good defaults tend to be a little more private and avoid the addiction to making numbers go up or achieving notoriety at any social cost. This puts fediverse instances like Epicyon at a slight disadvantage compared to ruthlessly commercial systems, but it’s an explicit trade-off in order to minimize the harms which can arise within social networks. So you won’t find any high scores tables or trending items.
In a browser if you navigate to the URL of your instance and enter the username and password that you previously registered. The first time that you log in it will show a series of introduction screens which prompt you to add a profile picture, name and bio description.
When you first register an account on the instance the first thing that you may want to do is to add more profile details and change your preferences. From the main timeline screen select the top banner to move to your profile and then select the edit button, which usually looks like a pen and is adjacent to the logout icon.
Add an appropriate description of youself, which doesn’t resemble the type of thing which would appear on a spam account. When other fediverse users are judging a follow request from you they will want to know that you are a real person and not a spammer or troll.
If you have any other fediverse accounts on different instances then you might want to add URLs for those. You can set the languages which you can read, as two letter abbreviations. This helps to avoid having posts from other people within your timeline which you can’t read.
You can set your posts to expire after a number of days. If this value is zero then the instance will keep your posts indefinitely.
If you are coming to the fediverse as an exile from Twitter then you may want to select the option to remove any Twitter posts from your timeline. Sometimes people want to make a clean break from Twitter and have no further involvement with it.
You can set additional contact details, such as email, XMPP and Matrix addresses. So if people want to contact you for private end-to-end secure chat then they can do so. The fediverse was never designed for end-to-end security - it is primarily for public communications - and so it’s better to leave secure private chat to the apps which are specialized for that purpose.
If you want to block particular fediverse accounts or instances then you can enter those in the blocked account section. There should be one account per line.
Within the filtering and blocking section you can also set a city which will be used for geolocation spoofing. When you post a photo, instead of removing all metadata spoofed metadata will be added in order to consistently fool the machine learning systems behind web crawlers or scrapers, and create a confirmation bias effect where the surveillance systems become increasingly confident in an erroneous conclusion. Setting a city somewhere near to your time zone is preferable, so that it matches your typical pattern of daily posting activity without giving away your real location.
If you are the administrator then within your profile settings you can also specify roles for other accounts on the instance. A small instance is like a ship with the roles being crew positions, and all members of the crew need to work together to keep the ship afloat. The current roles are:
Is allowed to remove posts and deal with moderation reports.
Editors can change the links in the left column and the RSS feeds within the right newswire column.
Artists can change the colors and style of the web interface, using the theme designer.
A counselor is someone tasked with resolving disputes between users of the instance. They are permitted to send DMs to any user account on the instance. Obviously, this type of power can be abused and so the administrator should choose counselors with care.
Devops are permitted to perform some routine administration functions, such as monitoring instance performance graphs.
On the main timeline screen at the top right of the centre column there is a search icon which looks like a magnifying glass. By convention within the fediverse the search function is also the way to look up and follow other people. Enter the handle (@name@domain) or URL of the profile page for the person that you want to follow and select search. If the account is found then its details will appear and you can choose to follow or not.
Once you are following someone then selecting their profile picture and then the unfollow button will remove the follow.
To make a new post from the main timeline screen select the new post icon at the top right of the centre column.
The format of the post should be plain text, without any html markup. Any URLs will be automatically linked, and you can use hashtags and emoji. Emojis can be added via their name with colon characters before and after.
Posts can have different scopes which provide some amount of privacy, or particular functions. To change the scope select the current one and a dropdown list will appear.
Is visible to anyone in the fediverse. May also be visible outside of the fediverse to anyone with an appropriate link.
Used to create a blog post. Blog posts are typically longer than other types of post, and are also publicly visible to anyone on the web.
At the top of the links column on the main timeline screen there is an icon to show an RSS feed for your blog entries.
Similar to a public post, but will not appear as a recent post within your profile. Unlisted posts can add a little more privacy to a conversation in that it will not be immediately obvious to casual observers. Often in practice this is all that’s needed to avoid trolls or unwanted attention.
A followers only post will only be visible to people who are following you. They will not be visible to people who are not your followers, or to other observers on the web.
A subtlety of this type of post is that people have different followers, so if you send to your followers and they send a reply to their followers then your post or references to it may end up with people who are not your followers.
Direct messages are only send to specific people, designated by their fediverse handles (@name@domain).
A reminder is a direct message to yourself at some time in the future. It will appear on your calendar.
A report is a type of post which is sent to moderators on your instance, to alert them about some problem. It is not sent to any other instance.
A shared item post describes a physical object or service which may be shared by people on your instance. Shared items may also be visible to people on specific named instances if that has been set up by the administrator.
A wanted item is a physical object or service which you want. These posts will be visible to other people on your instance and also to people on specific named instances if that has been set up by the administrator.
Attachments can use a variety of formats.
Attachments should be as small as possible in terms of file size. Videos should be no more than 20 seconds in length. Epicyon is not suitable for hosting lengthy or high resolution videos, although podcasts might be feasible.
You can specify a date, time and location for the post. If a date is
set then the post will appear as an event on the calendar of recipients.
This makes it easy for people to organize events without needing to
explicitly manage calendars. 
The location field on a post can be a description, but it can also be a map geolocation. To add a geolocation go to openstreetmap.org, find your location and copy and paste the URL into the location field of your new post.
Selecting the location header will open the last known geolocation, so if your current location is near this makes it quicker to find.
On a desktop system the main timeline screen has a multi-column layout. The main content containing posts is in the centre. To the left is a column containing useful web links. To the right is the newswire containing links from RSS feeds.
At the top right of the centre column there are a few icons known as action buttons, for show/hide, calendar, search and creating a new post.
On mobile screens there is a single column layout, and the links and newswire column content is available via action buttons.
Different timelines are listed at the top - inbox, DM, replies, outbox, etc - and more can be shown by selecting the show/hide icon.
As a general principle of navigation selecting the top banner always takes you back to the previous screen, or if you are on the main timeline screen then it will alternate with your profile.
At the bottom of the timeline there will usually be an arrow icon to go to the next page, and a list of page numbers. You can also move between pages using key shortcuts ALT+SHIFT+> and ALT+SHIFT+<. Key shortcuts exist for most navigation events, and you can customise them by selecting the key shortcuts link at the bottom of the left column.
The calendar is not yet a standardized feature of the fediverse as a whole, but has existed in Friendica and Zot instances for a long time. Being able to attach a date and time to a post and then have it appear on your calendar and perhaps also the calendars of your followers is quite useful for organizing things with minimum effort. Until such time as federated calendar functionality becomes more standardized this may only work between Epicyon instances.
Calendar events are really just ordinary posts with a date, time and perhaps also a location attached to them. Posts with Public scope which have a date and time will appear on the calendars of your followers, unless they have opted out of receiving calendar events from you.
Reminder is a special type of calendar post, which is really just a direct message to yourself in the future.
To create a calendar post from the main timeline, select the New post icon, then use the dropdown menu to select the scope of your post. Give your event a description and add a date and time. If you add a location this can either be a description or a geolocation link, such as a link to openstreetmap.
Selecting the calendar icon from the main timeline will display your calendar events. It is possible to export them using the iCalendar icon at the bottom right to the screen. Calendar events are also available via CalDav using the URL https://yourdomain/calendars/yournickname
The
links within the side columns are global to the instance, and only users
having the editor role can change them. Since the number of
accounts on the instance is expected to be small these links provide a
common point of reference.
This multi-column layout is inspired by the appearance of early blogs or the original Indymedia, which in turn was inspired by the appearance of monastic texts in which you would see comments in the margins in line with the main text. So you can be reading posts from friends but also keeping an eye on the news from RSS/Atom feeds at the same time.
Web links within the left column are intended to be generally useful or of interest to the users of the instance. They are similar to a blogroll. If you have the editor role there is an edit button at the top of the left column which can be used to add or remove links. Headers can also be added to group links into logical sections. For example:
* Search
Code search https://beta.sayhello.so
Wiby https://wiby.me/
* Links
16colors https://16colo.rs
Dotshareit http://dotshare.itThe right column is the newswire column. It contains a list of links generated from RSS/Atom feeds.
RSS is a much maligned protocol. It’s simple, and an excellent way to read news in a manner that’s convenient for you. The main reason for its downfall is that it’s difficult to implement targeted advertising - the dominant business model of the web - within RSS. It’s hard to spy on anyone using an RSS feed. So if we want the web to improve then supporting RSS ought to be a priority.
If you have the editor role then an edit icon will appear at the top of the right column, and the edit screen then allows you to add or remove feeds.
Feeds can be either moderated or not. Moderated feed items must be approved by a moderator before then can appear in the newswire column and be visible to other users on the instance. To indicate that a feed should be moderated prefix its URL with a star character.
Newswire items can also be mirrored. This means that instead of newswire items being links back to the original source article a copy will be made of the article locally on your server. Mirroring can be useful if the site of the RSS/Atom feed is unreliable or likely to go offline (such as solar powered systems only online during daylight hours). When deciding whether to mirror a feed you will also want to consider the copyright status of the content being mirrored, and whether legal problems could arise. To indicate that a feed should be mirrored prefix its URL with an exclamation mark ! character.
On this screen you can also set filtered words and dogwhistle content warnings for the instance. Filtered words should be on separate lines, and dogwhistle words can be added in the format:
dogwhistleword -> content warning to be added
dogwhistle phrase -> content warning to be added
DogwhistleWordPrefix* -> content warning to be added
*DogwhistleWordEnding -> content warning to be addedAs news arrives via RSS or Atom feeds it can be processed to add or remove hashtags, in accordance to some rules which you can define.
On the newswire edit screen, available to accounts having the moderator role, you can define the news processing rules. There is one rule per line.
Syntax: if [conditions] then [action]
Logical Operators: not, and, or, xor, from, contains
A simple example is:
if moderated and not #oxfordimc then blockFor moderated feeds this will only allow items through if they have the #oxfordimc hashtag.
If you want to add hashtags an example is:
if contains "garden" or contains "lawn" then add #gardeningSo if incoming news contains the word “garden” either in its title or description then it will automatically be assigned the hashtag #gardening. You can also add hashtags based upon other hashtags.
if #garden or #lawn then add #gardeningYou can also remove hashtags.
if #garden or #lawn then remove #gardeningWhich will remove #gardening if it exists as a hashtag within the news post.
You can add tags based upon the RSS link, such as:
if from "mycatsite.com" then add #catsSelecting the show/hide icon from the main timeline will reveal an extra timeline called Media. The media timeline shows posts which contain a picture, audio or video content. So if you are primarily interested in photos then this timeline can be useful.
If there is an description for the media then this also appears within this timeline. Selecting a photo will enlarge it.
The importance of moderation within social networks can’t be over-stated. In the early history of the web in which communities tended to be organized around forum software and mailing lists the typical pattern went as follows:
The pattern has been repeated many times. Online communities can take years to carefully build up and days to destroy. Having good moderation in place, with clear terms of service and enforced boundaries, can help to avoid failures or burnout. Being “nice” and accepting all content tends not to work out well. Such an arrangement is easily hijacked by people with bad intent.
If you have the moderator role then selecting the show/hide icon from the main timeline will reveal an extra timeline usually called Mod. Selecting this timeline will take you to the instance moderator timeline, which contains any moderation reports.
You can filter out posts containing particular words or phrases by entering the offending text and then selecting the Filter button. You can use the Unfilter button to reverse the decision.
If a post made on your instance has been reported as violating the terms of service you can remove it by entering its URL and then selecting the Remove button.
You can suspend an account on the instance by entering the nickname and then selecting the Suspend button. Accounts are usually suspended pending investigation into some terms of service violation. You can use the Unsuspend button to re-enable an account.
To block a fediverse handle (nickname@domain), hashtag or domain enter the thing that you wish to block and then select the Block button. You can do the same with the Unblock button to reverse your decision.
If you want to see what is being blocked at the instance level then select the Info button.
Most fediverse posts have Public scope, and various web crawlers routinely try to index them. These are mostly the usual suspects, such as BigTech companies, but also include lesser known crawlers such as the British Library. By default all web search bots are blocked, but the administrator account can enable particular ones.
If you are the administrator of the instance then to see the currently active web search crawlers edit your profile and select Filtering and blocking, then Known Web Search Bots. The most common ones will appear at the top. To enable particular ones add their name to Web Search Bots Allowed (one per line).
From the main timeline select the top banner to go to your profile, then select the edit icon. Open the Filtering and blocking section and then you can specify filtered words or phrases. Be sure to select Publish to finalize your settings.
You can also filter words within the bio of users making follow requests. This allows unwanted followers to be automatically rejected if their bio contains particular words.
From the main timeline select the top banner to go to your profile, then select the edit icon. Open the Filtering and blocking section and then you can specify blocked accounts or domains (one per line). Be sure to select Publish to finalize your settings.
Sometimes you may want to replace words within received posts. This can be for added clarity, to dissipate annoyance or just for fun.
From the main timeline select the top banner to go to your profile, then select the edit icon. Open the Filtering and blocking section and then you can specify replacements as follows:
OldWord -> NewWord
original phrase -> new phraseThese replacements are subjective, such that if you boost/repeat/announce a post then the original wording will be retained for recipients.
Content warning lists are lists of domains and/or keywords which can be used to append a warning if they appear in the content of an incoming post. For example, you can have a content warning added if a post contains links to satire sites, so that you don’t confuse them with real news and you don’t need to be familiar with every possible satire site. These types of warnings are opt-in, so if they don’t apply to you then you don’t have to have any.
From the main timeline select the top banner to go to your profile, then select the edit icon. Open the Filtering and blocking section and look for “Add content warnings for the following sites”. You can then select the types of warnings to be added to your timeline.
The fediverse is typically calmer than the centralized social networks, but there can be times when disputes break out and tempers become heated. In the worst cases this can lead to administrator burnout and instances shutting down.
If you are the administrator and you are in a situation where you or the users on your instance are getting a lot of targeted harassement then you can put the instance into broch mode, which is a type of temporary allowlist which lasts for between one and two weeks. This prevents previously unknown instances from sending posts to your timelines, so adversaries can’t create a lot of temporary instances for the purpose of attacking yours.
A general observation is that it is difficult to maintain collective outrage at a high level for more than a week, so trolling campaigns tend to not last much longer than that. Broch mode allows you to ride out the storm, while retaining normal communications with friendly instances.
To enable broch mode the administrator should edit their profile, go to the instance settings and select the option. Once enabled it will turn itself off automatically after 7-14 days. The somewhat uncertain deactivation time prevents an adversary from knowing when to begin a new flooding attempt, and after a couple of weeks they will be losing the motivation to continue.
Generic-looking user interfaces have become expected for many types of software, because they are designed to scale up to very large numbers of users and hence need to be as bland and inoffensive as possible. But small web systems don’t need appeal to a bland, corporate, imagined average user. If you are spending significant time using a social network then being able to customise it and really make it your online home improves usability.
Epicyon has multiple standard themes and if you are the administrator then if you edit your profile and open the Graphic design section then you can change the current theme for the instance. Users may need to reload the web page with CTRL+F5 in order to see the changes.
If you have the artist role then from the top of the left column of the main timeline you can select the Theme Designer icon, which usually resembles a paint roller or paint brush. This allows you to change colors and values for user interface components.
This is intended to add Freecycle type functionality within a social network context, leveraging your social connections on the instance, or between participating instances, to facilitate sharing and reduce wasteful consumerism.
When creating a new post one of the scope options is called shares. You can describe an item or service that you are willing to share.
Sharing is primarily intended to not require any monetary transactions, although prices can optionally be added. There are no payment mechanisms implemented and if that is required then it is recommended to include details of payment method within the description.
This is the opposite to adding a share in that you are making a post which indicates that you are wanting some particular thing or service.
When new shared items are added then in the left column of the main timeline screen there will be a section showing recent shares.
Any items shared or wanted will appear within timelines, which can be viewed by selecting the show/hide icon.
If you are the administrator of the instance then you can specify other instances with which your local shared items may be federated. Edit your profile and select the Shares section, then add the domain names of the instances to share with (one per line). If other instance administrators also configure their system to share with yours then this is the ideal mutualistic situation, increasing the set of things being shared.
The technical implementation of federated shared items currently does not use ActivityPub, but instead a pull-based system more comparable to RSS/Atom. This is so that the people doing the sharing always remain in control of what they are sharing, and can withdraw a share at any time. A pull-based implementation also makes things considerably harder for spammers.
To search, select the magnifying glass icon from the top right of the centre column of the main timeline. This will take you to a separate screen where you can enter your search query.
Hashtag categories
If you select SHOW MORE at the bottom of the search screen then this will show all recent hashtags, in alphabetical order. If you have the editor role then selecting a tag will then allow to to assign a category to it. In this way you can build up hashtag categories as a way to group tags together under subject headings. For example, cake might be under a food category.
The hashtag categories are published as an RSS feed at https://yourdomain/categories.xml, and editors on other instances can add those feeds to their newswire. This enables the categorization of hashtags to be crowdsourced between instances.
Searching for a fediverse handle or profile URL
If you enter a fediverse handle or a URL corresponding to a profile then the system will try to find it. If successful then a summary of the found profile will be shown, and you will have the option to follow/unfollow or view the original upstream profile page. If you are already following then a different screen will be shown with more options available.

Since the web interface of Epicyon only needs HTML5 and CSS, it can work with browsers which don’t implement javascript at all.
Screenshots within the preceding sections all assume that you are using a common graphical web browser. However, it is also possible to use Epicyon from a shell browser, such as Lynx. This may be better suited for use with screen readers, or if you want to check your social media while logged into a server via ssh.
If you are using Lynx then you will need to ensure that it is configured for the utf-8 character set, and that you have emoji fonts installed (eg. noto-fonts-emoji). Edit your lynx.cfg file (usually in /etc/lynx.cfg) and set:
CHARACTER_SET:utf-8To avoid annoying questions you may also want to set:
ACCEPT_ALL_COOKIES:TRUEAfter logging in you will see a menu, which are shortcuts to different screens.
Timelines will look something like the following.
The great thing about running a small instance is that you can do things in whatever manner you prefer. What follows is a few guidelines which may help.
Have a working backup system
Keeping backups is very important, and fortunately with Epicyon this is a simple process. The Epicyon installation consists only of files in a directory. There is no database. So just backing up the directory where it resides - typically /opt/epicyon - is all that you need to do. Once you have a backup system in place, test that it works.
The fediverse is not an open source Twitter
This sounds like a trite comment, but if you have members on your instance coming from Twitter and expecting it to be the same sort of thing then they will be disappointed. A major difference is that the fediverse is more about conversation rather than one-way broadcast. Sites like Twitter encourage you to become an “influencer” and adopt a style of communication where you are shouting to a large audience without much expectation of dialogue.
On Twitter there is an algorithm which will make follow suggestions and dump all manner of aggravating trash into your timeline. On the fediverse if you want to connect with people then you will need to be more proactive in going out to find the others. There is no algorithm trying to guess what you want without your participation.
Robustly remove bad actors
If people are creating a problem or bringing trouble and are not amenable to changing their ways, whether they are members of your instance or not, then be prepared to block or suspend their accounts. Remember that trolls will destroy your community if you let them. Define your terms of service and apply it consistently to anyone interacting with your instance.
Curate your experience
Add links to the left column and blog or podcast feeds to the right. Choose links which are relevant to your community so that useful information is one click away. If you have multiple people on your instance then assign roles to them so that they have a stake in maintaining a good experience.
