Downvoting on HN is poorly implemented. It creates an unstable initial condition for a new comment. Downvote from initial 1->0 cascades into a snowball effect for ganering downvotes from other users who are pursuaded by the gray text. Similarly, if is upvoted from 1->2, then you have a strongly positive comment that will most likely stay positive. Delaying the visual indicator of gray text for 1 hour would solve this problem. As it stands, it rewards pathological downvoters who continue to degrade healthy discussion on this site.
