You'd sub to one meta c/memes or c/news and see a combined feed of all known instance's versions. Post to whichever you want, show up in the meta (if you want).

If you still want to block from the meta sub or individually sub to c/memes on ABC instance, you could do that. Moderation would be subject to the instance the user posted on, subject to broader instance admin's defederations and stuff.

Idk just a quick idea. Decentralization is good, but a little bit of... aggregation like this could go a long way without actually centralizing power. Could help communities (big and small niche) to grow.

Isn't RSS what you're describing?

Not exactly but that's a good way to think about it in essence. These metacommunities would be purpose built for and integrated into lemmy though, otherwise it would just be RSS which doesn't address the fragmentation issue.

This is a fantastic idea. I really love the decentralization of Lemmy, but I do feel the side effects of having many copies of the same subject on different instances.

And to your point, I'd love for niche communities to have a larger audience. I need somewhere to post and read about project zomboid.

Sounds like a whole app idea.
