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.
https://github.com/LemmyNet/lemmy/issues/3057
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.
In theory, yes. But in practice, any decent-sized instance is already exposed to all communities of the other decent-sized instances.
And you can always “introduce” your instance to communities that you find with external tools, like https://lemmyverse.net/communities
Keep in mind that joining a larger instance also has its cons, like more server load (lemmy.world is having issues with this), moderation, etc.
Wow, that is pretty neat! And thanks for introducing me to the lemmyverse explorer. This is honestly all pretty exciting.
