why are there no active casual conversation communities?

like, i'm just trying to post random content. normally i post stuff to /c/onehundredninetysix@lemmy.blahaj.zone but this topic feels more mature, less silly.

/c/casualconversation@piefed.social only has like 15 votes per post so it's not very active. meanwhile /c/asklemmy@lemmy.world has more like 70 upvotes per post on average. why is the casual conversations community so inactive?
