Title basically. I was here at the very start of it all and really enjoyed it. However I felt it lost its uniqueness within a few months of mass migration and started turning a bit like reddit again so I deleted my old account. However Reddit has only gotten much much worse since, and Lemmy has stayed about the same. So here again.
It has gotten much better. More content and general activity and nutjobs at .ml and similar got mostly isolated from the rest of the network.
I think fediverse is really shaping up as a strong reddit alternative. Most pop subjects are mirrored here and the vibe is very similar to early reddit so there no real reason to go to reddit other than super niche communities like of a tv show or something.
Most props go to the lemmy.world team as it kept a consistent big sane network running that keeps the project stable! If .world never happened I think Lemmy would have remained cess pool of social rejects like most reddit alternatives like Voat or lemmy.ml
