The Fediverse if a complicated concept, that looses a lot of the appeal that Twitter/Reddit has, we need more coordination between instances, and less of a scattershot approach to communities. This obviously goes against the goals of the Fediverse where you want several similar communities on different instances to make the system far more robust.
Then we need a killer community, a community that people has to have, that only really work on Lemmy, and not on Reddit.
Mastodon mostly just needs more users, especially celeberties, then users would come.
I read something about ActivityPub 2.0 being pushed for more feedback from the developers of Instances talking, so hopefully that brings more talk and direction between instances.
Lemmy would be amazing if it had some unique communities that people have been looking for, for years on Reddit. It could be a way to get Lemmy to grow.
I know there is crossover between places like Mastodon and Lemmy as at the moment I'm using Mastodon to talk to everyone on Lemmy but certainly could be improved.
Lemmy overall feels like old reddit when it was still run and filled by people who cared. Names are familiar, everyone rather(in some places) chill, and the server is on fire half the time. I forgotten what it was like to start to know people online. Reddit is too big to ever learn a name again unless its a "human" on the front page again. It's kinda nostalgic.
Yeah it would just be nice to have some more niche communities being run. Maybe I should help start those niche communities or something but I’m not really using Lemmy anymore but still love browsing the content
