I'd love to see a No Assholes rule on HN. By that I mean if an admin saw a post that was asshole-ish, the poster account would be disabled. It would encourage polite discussion. The current point system mostly encourages point-baiting and groupthink/PC-ness. Internet posting seems to encourage rude behavior, and it's exacerbated when you have a bunch of geek personalities who often lack good social skills.
