Well see then we get a whole bunch of new people creating favorite threads that are usually low quality, and that I have seen 1,000 of the same thread created already.
If its a well thought out thread and it creates a discussion, then sometimes we might let it slide.
I mean you have to agree, if you have hundreds of "Whats your fav color?" threads, it would get boring and annoying. People who have been here awhile know what kind of topics have already been recently discussed, so there arn't the same threads done time after time.
