Yeah, Lemmy isn’t quite at that critical mass where the niche stuff is active. That’s one thing Reddit was truly wonderful at, because it had enough people that even the niche stuff stayed active. Like if only 0.01% of people are interested in something, and a service only has 1000 users, there‘s a good chance that you’ll be the only poster.

I've found some super cool niche communities using the 'random community' search, which i think is a Voyager app specific option cause I'm not seeing it on desktop. I definitely recommend the Voyager app
