I mainly tried lemmy.world, lemmy.ml, beehaw.org and a few others. I did try them with and without “all” and it was cumbersome regardless. Either I was served posts with zero or negative upvotes that to me do not classify as “hot” or my feed did not update at all.
What’s weird to me is that kbin.social was the only one I tried that was not affect by any of this strangeness.
I was also really unhappy with it. Then I tried kbin.social. It’s not a lemmy instance, but also uses the fediverse so you can still see and interact with posts from other lemmy instances.
