A multi-community would be all communities with a certain name, across all instances. It would prevent powermods from being a problem on Lemmy. i think it should be notated with m/<insert name here>, just like communities but with m instead of c.

  • Let’s make it turtles all the way down; allow for federation at the community level, subject to the federation guidance at the instance level. If memes@lemmy.world and memes@foo.bar are sufficiently similar to share content and as long as lemmy.world and foo.bar are federated, then content from both communities appears in both communities.

    If moderation issues arise or if the communities diverge in interest, they can split. Users can pick either or both communities to interact with. The world goes on.

    Of course, I have no idea whatsoever how to do this, and there’s probably a better idea already in the pipeline… but if it works at the macro level I think it’s got a shot at the next level down.
