I've been on this part of the fediverse for years (via lotide rather than lemmy or kbin, but I've been here), and kbin itself is incredibly new. I'd never heard of it more than about 3 months ago, and I'm constantly on the watch for new stuff because I always believed this part of the fediverse had huge potential.
Honestly, considering how new it is, kbin is shockingly good. Go back and look at reddit 3 months into development!
