I'm curious if the volatility of upvoting/downvoting is (or could be) used to rank comments. I've posted some musings that I thought were rather insightful and was surprised to see them settle on a score of 1. I suspect that they were being endorsed and denounced repeatedly because they were controversial.
But it hit me that the most relevant or thought-provoking posts may run counter to one’s worldview or deeply held beliefs, so in effect could be catalysts for moving the conversation forward and avoiding groupthink. I know that those are the sorts of pearls of wisdom that attracted me to Hacker News and Paul Graham’s essays initially (though I realize that he no longer decides these things).
Would it be possible to visually indicate the total number of +/- votes per post, or use that as a weight in the scoring formula? This would be separate from the controversy penalty (that prevents flame wars due to too many comments).
If you want to mention some links to comments you think the idea would apply to, we'll take a look.
