Generally, you do not need multiple accounts on different lemmy servers. You can “use” the other servers with one account. And, that you have multiple different servers, is by design.
Or are you referring to defederation, when you are writing about “seperation”?
Maybe Lemmy won’t be the right fit in the longer run, although development seems pretty good currently.
Whats more important to me is, how the adoption of ActivityPub evolves and the Fediverse developes in the long run.
I am a bit split. I too find it a bit annoying to scroll past 80% of the posts. On the other hand, sometimes I see that there are new comments (which lemmy shows) under a post about an interesting topic.
Fell up the stairs. Had to visit a hospital, got a splint.
Oh yes Aegis Authenticator. Its so essential, I forgot. Plus Bitwarden Passwordmanager
