Communities on different instances about the same topic should have the option to essentially federate so a post on one appears on all of them and opening any of them shows you the comments from all of them. This way when lemmy.world is down its not a big deal because posting to any news community federates to all of the communities instead of barely having people see your post. Federation could be decided by the community mods and the comments can have a little “/c/communityname@instance.name” on it so you know which community the comment was originally posted on.
I like the idea. I suspect it would make moderation a challenge but it sounds pretty useful
This was the idea behind MultiReddits if I’m not mistaken. In which case a simple operator like:
Fediverse@lemmy.world+Fediverse@lemmy.ml
Could get baked into the Lemmy core to allow this to work.

That’s the way I think it should work.
That’s still just two separate communities. Like a filter. That’s fine. That’s not what OP is suggesting though. What OP is suggesting is much more extreme.
What are MultiReddits and how do they work?
Basically you can see multiple subreddits of your choosing as if they are a single subreddit.
Oh wow, that can be beneficial to some people. Thank you for taking the time to explain
Here’s how it’s done. You just add a +, then the other subreddit. Now your view has 2 subreddits.

If all federated communities could decide upon to regulate same rules, every one of them could be moderated by their own moderators. But the problem I see here is the things that’s being federated is in reality server itself which means it would be impossible(not sure but at least not necessary) to do such a thing. But anyone can easily build an app to collect posts from same communities, it does not require to play with activitypub, just lemmy api.
