Thanks! Did I get these right? - HN uses time decay to reduce score of older comments. While, Reddit uses wilson confidence interval to give provisional ranking for comments. - Wilson confidence interval is useful when you want prospective score i.e. if comments are likely to get more upvotes in the future. - For definitive score, (lets say, user played a game and has a score), HN's time decay will work better than wilson confidence interval?
