The ranking system is based on points; a given. But I would argue that a weighted rank(Comments + Points) is a better ranking system. More conversational threads indicate greater interest(not always, it could be one guy spamming). But if you can find a way to weigh the rank as to include comments; yet exclude abuse, your ranking system would be much more superior than HN's.
