Biggest problem for me is that the community I'm most active in (/r/hockey) didn't even try to move away from Reddit and since that's where I'm the most active, I don't make those posts here because I can't, its just not worth it because nobody will see it. Same goes for some video game communities, they also did not even try to move and some of the devs actually read those niche subs, so there's no point in moving. I like kbin/Lemmy, but its just not at the same level with some of those subs.
