I did read it but all I saw in rejected is "Disqus", I didn't assume the whole premise of an upvoting system was considered outlandish, I still think that an upvoting system isn't a bad idea, but then again it could be a horrible idea that will never be implemented for reasons that could be server side, I still hold the same beliefs that upvoting leads to a better user experience overall as finding a discussion about a topic/theory or a humorous comment will be easier if that comment is upvoted and well-received.
