I upvote articles that I find interesting or want to follow up on later, as the vote puts them in my "saved stories" list. I used to flag blogspam and like, but that got my flag button disabled for a year or two. I downvote stupid posts and obnoxious posts. I upvote interesting posts and posts that make me think. I see a lot more of the former than the later, the last few weeks... I also tend to downvote any post sticking up at the top that doesn't seem highly worthwhile. Kind of like that recent reposting of the Fogus list of papers every programmer should read, where the top-rated comment was by a guy who complained about the title and indicated he hadn't even read the article.
