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.

    This is a really good idea. Multi-instance communities would not just provide content redundancy, but also some load balancing. Each multi-instance community would become it’s own little CDN. Duplicating the data across instances does pose a problem of bloat, but I think the benefits outweigh the risks.

      Bloat can be slightly resolved by just archiving/delete the data after a certain period or let the poster set the deletion date based on reputation. Just thinking out loud.
