Hexbear was around for a couple years before federation was a thing so a lot of people only ever post there.
Also, and I say this as a frequent Hexbear poster, the average Hexbear user has read zero theory and just wants somewhere lefty to shitpost. There is not a ton of overlap between them and people that use Lemmygrad/Leftypol/etc

Leftypol is still kicking well enough, all the spinoff chans are mostly dead as far as I’m aware

Sorting by Hot also works pretty well, good mix of new posts and popular ones

(logging in to my two year old account with four posts) We’re so back
