I feel sorting top 6 hours would make more sense for me if I were sorting posts/coments within a community itself, because I would want the newest posts, but at that point I just defualt to new anyways.
But when searching for communities, personally i’m not for sorting it by hours or days because I want to make sure a community has an ok track record of being active, but at the same time i’m not wanting to keep a monopoly so that’s why I don’t go out of my way to sort the communities by top year or something like that because then we’d have another Google. I strive to strike a balence.
