https://lemmyverse.net/communities
Also native search works pretty well https://sh.itjust.works/search?q=cat&type=Communities&listingType=All&page=1&sort=TopAll
These should help. Definitely agree about the amount of content. There’s a lot of subs that haven’t even migrated over yet.
Even if you do nothing else, make sure to upvote content and comments, and subscribe to communities. Bringing content over from reddit (or even just googling stuff) to the new applicable community would be extra helpful (a lot of empty communities at the moment).
Things keep looking better here, so I’m optimistic about lemmy.
