I’m not interested in dismissing your feedback, but I do kind of agree with the point made by person you’re responding to (I don’t agree with the rhetoric).
By sorting by hot, I get a lot of low-engagement posts with 5-20 upvotes and 0 comments. It’s just not the kind of content I want on my feed. And while this is all anecdotal, Lionir also responded to you with (hopefully honest) confirmation that active > hot for most users.
