If you're worried about the signal-to-noise ratio, then I suggest you don't post things that have been posted and discussed about a gazillion times before, as this too is cluttering up the main page. You don't have to like every single article on the main page. Hacker News wasn't made just for you. If people upvote, then clearly they disagree with you on the article. Disagreement is ok, even necessary for a useful discussion. If you've read all the articles on the main page then I suggest you either read old threads on the topic of downvoting or just spend your time more productively by doing something creative rather than complain.
