Your comments

Well, Chris, I did offer a second solution at the end there. To keep anonymity we shouldn't let people know exactly who downvoted who. But what if when you hovered your cursor over a person's caption it would pop up with a pie chart showing how many captions that person upvoted vs. how many they downvoted on that particular photo. That way you could see their overall contribution vs. their desire to downvote others to make their comment look better. Ya see what i mean?
That's definitely a good idea. Its discouraging to get downvoted into the netherrealms when you feel like it was a decent caption. I guess we'll have to wait and see what the admins do about it.
