I honestly do not understand when people complain about Lemmy being too empty. That's not my experience at all, not even close! My subscribed feed is pretty tame (intentionally), but if I switch to all, I can scroll and scroll until I'm like "maybe I should take a break" and I'm still only seeing posts from like 3h back. There is so much going on here, how are people going around saying it's dead?
Are there bigger versions of the same communities elsewhere? One of the problems at the moment is duplicates, and finding the one where people have coalesced can be be hard, sometimes just dumb luck.
