After going through a few pages on the main page (or until I start seeing posts I’ve already seen) then I go to the “new” tab. I read a lot of those and upvote the ones I think should be visible on the front pages. If it’s something that’s really interesting/useful I try to comment so as to give it a bit more visibility. I like to think that most HN users do the same :-)
