There are very few lemmy communities with enough participants to be anything like reddit. There is or was a NSFW lemmy server (lemmynsfw.com) though, which might be an ok place for your NSFW stuff, if it’s still around. I’m not trying to be discouraging of unwelcoming but Lemmy is simply not a bustling metropolis like some of us might wish for. It’s more like some random lost souls wandering around in the desert, with a few slightly populated areas here and there. Ask Lemmy, where you are right now, is one of the denser such pockets and there’s not much going on here either.

Anyway, welcome to Lemmy. There are things to like about it but it’s more like sitting around a campfire with a few other people, than being in a dance club. Join us and toast a few marshmallows.
