User accounts are fragmented and just because you signed on at lemmy.world doesn’t mean your account exists on lemmy.ca.
https://github.com/LemmyNet/lemmy/issues/1985
Communities are fragmented and /c/games on lemmy.world is completely different than the one on lemmy.ml with its own users, set of posts, etc.
Lemmy does not currently allow for instance or user migration.

Nor does it allow for shared communities (ie the aforementioned /c/games is unified across multiple instances)

We are in the early days. If you’re eager feel free to join in the development on these any many other core issues. There’s real potential here.
Imho a better option, which I’m sure if Lemmy is successful will get there, is a central app but with a public codebase and a federated ownership. A central platform owned by the people for the people.
What does “central app” mean to you? You’re aware the code base is shared right?
That’s literally what this is
