On the other hand, if you are an article writer and add a "discuss this on HN" link in your articles, you should remove the link as soon as you get a good ranking. Or actually don't ask people to discuss at all, because it is harmful, just ask them to vote and have your own comment system for discussion.
HN basically reinvented "sage", the concept from 4chan and its Japanese origins where people sometimes comment on a thread just to get it closer to the comment limit before it would no longer be bumped up to the front page when replied to.
