User accounts are fragmented and just because you signed on at lemmy.world doesn’t mean your account exists on lemmy.ca.

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.
honestly i feel that lemmy should just have been matrix-based rather than activitypub, sure it’s nice to have native federation with mastodon but the forum structure is PERFECT for the matrix model.
By using matrix you would have communities be independent of servers (thus actually owned by the moderators and not the instance admins), and there would be a possibility of decentralized user accounts somewhere in the far future.
