I migrated from reddit like a lot of folks. I’m using kbin.social, but it seems I can also see posts from people at places like lemmy.world. How many different instances are there? How does the federated model work? So far I like what I see, but I’m also just trying to understand how things are integrated here.
Joking aside it’s my understanding that instances grab new content from communities/magazines it knows about, as much as possible. From what I’ve been seeing, federation in both Lemmy and Kbin can be a bit wonky though, I’ve gone back to Lotide.
Instances are like subreddits where the mods are top level admins, and there is no central admin above them. Anyone who wants to create an instance can host their own server. Communities can be duplicated between instances so you could have dozens of c/gaming communities rather than a single community for a topic which stifles engagement a bit. The cost of hosting is paid by the admins of an instance or by donations. Sponsors and ads are not currently feasible.
Unmoderated instances allow any new instance’s content to be displayed for their users.
Instances are like Reddit, Twitter, instagram, etc. Each instance has certain rules that may vary from the parent they forked from (see beehaw vs Lemmy.ml). Those instances will then have a structure like subreddits, posts, comments, etc.
Lemmy is similar to Reddit. Communities (c/*) are subreddits
Mastodon is similar to twitter. Microblogs are tweets.
Instances are like smaller Reddits. Communities (lemmy) and magazines (kbin) are like subs. You can subscribe and participate in any c/ or m/ as long as their instance is federated with yours.
To add to the fun, we can also interact with users on Mastodon (similar to Twitter), Pixelfed (like Instagram), or any other ActivityPub-enabled instance that federated with us.
To my mind, a better analogy is email. It doesn’t matter which platform (provider) you use, you can interact with anyone on almost any other email platform. Make sense?
a new instance doesn’t know about any other instances at first. when someone on the new instance, instance A, searches up a community on instance B, instance A now knows about the existence of instance B and starts pulling content. the more communities people on instance A subscribe to, the more of the Fediverse instance A sees.
what this means in practice is that a community can be hosted on any instance, and people from any other instance (that isn’t blocked by the community’s instance) can post and comment on it seamlessly. the community you posted this to is hosted on lemmy.world, but you have an account on kbin.social. and i have an account on sopuli.xyz!
this means that you get the freedom to pick whichever instance you want to set up your account. since each instance is its own independent website, if one instance goes down, the rest of the network isn’t affected. you could even set up your own instance on your own hardware! different instances have different rules and vibes, and if one instance is misbehaving (e.g. mods have lost control, the software is glitching and spamming other instances with too much traffic, there are nazis), other instances can block it temporarily or permanently.
as for how many instances there are, FediDB lists 1,175. no instance sees every other instance, so there isn’t an optimal one to join like some people have asked about
You are not logged in. However you can subscribe from another Fediverse account, for example Lemmy or Mastodon. To do this, paste the following into the search field of your instance: [email protected]
No such thing. Ask away!

That’s the fun part, it doesn’t.

Oh cool! I didn’t realize lotide federates with the latest version of Lemmy again.
I know it was pretty frustrating for a while there, but it became clearer that everything was having federation problems.

This was a great explanation, thank you.
No problem. Enjoy the new world :)

You can subscribe to any community no matter what site you use.
You can subscribe to any content your instance federates with.
Wrote this once so I’d never have to write it again. lol Here’s how I word it:
