yea the reason to want more users is for niche communities, I don't need a billion people just for memes or news, but when you subdivide your users down to niche communities suddenly you'll want more
I wish there were more people on Lemmy talking about Deus Ex, The 7th Guest, DOS games, Randomizers, or specific TV shows that I'm currently watching (Reddit always had a pretty active sub for each and every show)
