Chicken and egg problem. Communities are too small to have conversation, so no one goes there for conversation. I’m a hockey fan. On reddit r/hockey is huge and busy, but so are all the team subs. Whereas on lemmy, if I post to the team sub, it’s just crickets. So I suppose that if all the hockey fans all hang out in !hockey@lemmy.ca together, we might have critical mass for a conversation now and then. And we can worry about our team subs later, if the general community outgrows one place.
