Oh man. I could see something like this really catching on if it was handled just right. I'm not sure exactly what that would require, but I think if it showed the comments before / instead of the usernames, it would improve the game. Or maybe if it was played in rounds or something, like those "best caption" games. I don't know. But if you're into it, keep it up. If you made this into a whole website or a social network app, it could do really well.
