I would say lemmy is in one of the better positions of the fediverse, as far as being useful.
IE IMO the facebook/instagram equivelents you need an insane critical mass to get anywhere, because simply put, in a crowd of 100k in the globe, you probably don’t have your friends/family… IE the people you use those apps to see.
Mastadon… a little bit better as you are looking for general stuff, but still the main drive of twixxer is reading on celebs, noteworthy figures etc…
Lemmy… well sure in 100k people you’ll absolutely find some with interesting discussion on politics, gaming, plenty of memes and cat pictures etc… Obviously without a real huge constant growth we won’t be the ideal place to discuss super niche topics (least ones that aren’t only discussed by a handful of geeks). So barring either super narrowly focused migrations, or major exedus’s lemmy will probably lag behind reddit when it comes to say discussing specific games/movies, but will continue to have great content in the overall gaming/movie/meme topics.
Well it’s the concept of not being fediverse. Point is one great developer running everything is awesome. However he’s tying it into bluesky… which also while it seems great on the surface right now, is still basically positioned that if it sells out it could be just as corrupted as Dorseys previous project
