Maybe this is unpopular but I'm getting tired of opening lemmy and having to scroll past the same post that I have viewed already, half of the posts on the front page are 2 or 3 days old.
Hot and active feeds are currently broken for a lot of big instances. It should be fixed in the next Lemmy server version. For now use New or New Comments. Growing pains of being such new software and such a huge, sudden adoption.
I really don't mind the growing pains .... enjoy what we have now ... there might come a time in ten years when we'll look back on today as the best of this new social media.
