The best thing I can think of is flagging, which would just mean that if you agree with me, when other posts like this come up, leaving a comment suggesting that it goes against HN's guidelines, which it does IMO by not being interesting. This might result in it still hitting the front page but spending less time there, which would probably be better than going outside of how HN currently works, since HN already strikes a good balance with its curation.
