Mr. dang, can I use the opportunity to suggest to turn the tiny upvote and downvote arrows into links, separated by sufficient distance? My fingertip is 15x larger than these arrows and it takes quite a bit of precision to hit the right one. I bet, half of upvotes and downvotes are erroneous for this reason.

The "undown" or "unvote" link that appears tells you which one you hit. I appreciate how little space they take up. If you're doing it with touch just zoom in.
