Feature request: Since upvote and downvote are asynchronous, could what number your vote is display?
Dear Woot technical staff,
Since the upvote and downvote operations will usually occur well after the page has rendered, and are definitely asynchronous, I think it could be rather helpful to have a small, no-frills display (maybe just by setting an alt, or title attribute or other hoverable data) of what number vote the user's actually was. For those that understand the leaderboard mechanics, it may make a difference in whether they wish to leave it in place or rescind it.
I suppose if the update mechanics were sufficiently predictable that you could give us an idea of where our vote stands in relation to the newly displayed value, that would do the trick too.
