If you recall reddits growth many of their communities evolved as offshoots of a single generic community. This made it easier for people to see discussions they normally would not get involved in, and once the posts in a similar category reached critical mass it moved to a sub Reddit.
I think people are recreating their niche communities here but they are floundering since the user base is still pretty small. Maybe it’s best to post to the “big” communities until the time is right to move to smaller, targeted communities?
even more absurd are these communities where someone invested lot of work into creating the sidebar, created rules that resembles constitution for mid-size country and there is zero posts, not even from that founder.
sometimes it really seems like “i proclaimed myself a king, the subjects surely should come now, right?”
