I get the general gist, like email different instances can communicate with each other but beyond that I’m lost.

I’m sorry if this has been asked 1,000 times lol

Edit: Thanks for the answers this makes more sense now :)

    So each instance within the fediverse can communicate with each other, but how do things like the feeds work? Since there’s no algorithm is everything from Lemmy.world only going to show up on the popular feed (if I’m on that instance) or can other things like lemmy.ee or whatever also show up?

    And can I comment on posts from a different instance or does that vary per instance?

    Sorry, last one. I noticed there are things like music streaming and video sharing instances within the fediverse, so could Lemmy theoretically allow content from those instances to be cross-posted here?

    Basically to me this feels like a super modular super media platform that has tons of parts that can plop in and out of the system as needed.

      how do things like the feeds work?

      So what actually happens under the hood is when one instance communicates first time with another instance it builds some local cache of that remote instance. Then, when you open “All”, you get everything from your local instance + things cached/requested from other instances. Admins can defederate an instance, in which case you would not see anything from it.

      Since there’s no algorithm is everything from Lemmy.world only going to show up on the popular feed (if I’m on that instance) or can other things like lemmy.ee or whatever also show up?

      Everything federated will show up.

      And can I comment on posts from a different instance or does that vary per instance?

      If federated, you can both see and post both posts and comments on any instance from your home one.

      could Lemmy theoretically allow content from those instances to be cross-posted here?

      It could. More than that, Mastodon users currently can both subscribe to Lemmy instances and post/comment. It looks kinda weird since they mention post author/community or whomever they answer to in a comment, since they see it as if it looked like Twitter.
