there’s no communities for my niche interests!!!
more like “i want a ready-made community where other people already putting effort into posting cool and intersting stuff, and all I want to do is sit on my ass and shower posts generously with “”“muh upvotes™””“”
And then do that for 15 other things you are into but don’t have their own community. So you can go take a dump and scroll through dump-time after which you go back to work. Or alternatively, to managing the 15 communities you now are responsible for.
