They kinda do though. I can’t post about my gaming niche in a gaming community because it’s barely tangential, and still haven’t found 99% of the communities I had on Reddit.
Simracing. We don’t relate to typical gaming at all. It’s all high end hardware, all very specialized and typically doesn’t interest normal gamers.
Subreddit mods are very against Lemmy or anything that moves them off the platform. The absolute butthurt rage for weeks after the protests proved that one right.
Mostly I just don’t see this platform as an alternative for medium sized communities. It works for large ones where there’s enough people that after a move if 25% transfer then you still have a lively community. Or for small communities where you can get 70%+ to move. But those mid size, 100k users on average communities trying to get them to move just ends up with a ghost town here.
I’m actually a mod over there, but as a general consumer of content, there’s not enough to make it a viable community. It’s seen a little more activity recently, but is overall a fairly small and dead community.
