I upvote what I consider to be good points. That is not always something I agree with. "Disagree but made me think" is about the highest praise possible on HN. I downvote things that I think are factually wrong, or things that are opinions but are stated as fact and are (IMO) wrong. I also downvote hostility, aggression, name calling, flamebait/trolling, blatant politics, spam, bad faith arguments. I sometimes downvote arguing without actually listening to the parent's argument.
