I think this sort of unfulfilled promise has been the biggest obstacle of my full scale adoption of a reddit alternatives.
As a non-typical Lemmy user (No interest in privacy, piracy, Linux, FOSS, Web Dev, SW Dev, Veganism, or discussing political theory with strangers online) finding active communities in topics i am interested in (basketball, football, hip hop and rap, martial arts, boxing, mma, PC building, relationships, kink, and the specific humor and nuance that comes with being a Black person on the internet) has been a struggle.
Many of those communities have two people or less posting in them or don't exist at all.
People are talking here but not about things i wanna discuss and that's disappointing so i have a hard time "sticking" if that makes sense
