Ah, I guess I can only do so sometimes as well. So feel free to leave a comment, I'll register your downvote then you can delete your comment.

This experiment in ad-hoc polling is kind of showing the limits of the idea.

I think an easier way would be to make two posts, Vote one up for each choice. Wouldn't prevent double voting but the difference between the two would still be accurate.

I think the rule is you need more than 500 karma and can't downvote a reply to your own post.

I cant vote down and Ive been here for about a year.
