Yeah HN down votes seem totally random to me. On reddit I can usually guess why I was down voted (advocating a viewpoint that goes against that subreddit's bias), but on HN I have no idea. I've been upvoted on things I would expect to get downvoted on and vice versa. It's so random I just ignore it as noise.
