Hi friend, it's not my instance and not my business, but have you considered that lemmy maybe doesn't have the userbase to support the number of highly niche and specific communities you've been making lately? I'm concerned that our own /c/gaming in total is probably getting less posts than an /r/rpclipsgta would get on Reddit. This, in my mind, will kind of make lemmy look like a ghost town, with hundreds of empty comms at less than one post per month, posts which would all probably fit in and be voted up in their relevant umbrella communities, until we get our userbase up and actually start experiencing crowding in those umbrella communities. Have you considered things from this angle?
Haven't made them, promoting all the options of new communities. Giving people choice is the point, people will choose to either post to your gaming (or a different gaming) and rpclipsgta, or both. Even if they are niche, I don't see how you get to the conclusion of one post per month, as that isn't even happening at all right now with a small user base, not taking to account future growth. I have considered things from that angle, and saw that that isn't happening now, and we will see what happens in the future too
