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’m hopeful niche interest communities migrate over to smaller instances, I’ve seen some niche interest instances pop up slowly but surely thankfully.
I want all like communities to have their own instances, but that’s probably just my organizational brain wanting to group things.
I agree. Mine is mainly for books and writing so I hope more people with those interests (and maybe those communities) will set up shop over here. Idk beyond that, I guess reaching out and offering them a space?
