Idea for a fix: Perhaps HN should have separate karma to reward upvoting on /new on links that are successful later, much like reddit used to have (or still has?) trophies for correctly predicting that a link reaches the frontpage. If there is more incentive to vote on new items you get more accurate estimates of the link quality, and it also does warrant reward to sift through lists with such a low SNR.
