Hot or not to me is something of a train wreck, but interesting. One thing about it is the quality of the picture affects your rating. If it is all blurry and crapy you are going to get a lower score. But what happens is cutish people with low self esteem, like a lot of the teen age girls on these sites, don’t want their picture taken. This insures they get a crappy picture, causing a low score, leading to an even lower self esteem.
That said I haven’t put up a picture yet. Buddy of mine put his wife’s picture on Hot or Not, but didn’t tell her. Then he told her when she got a high score. My wife threatened bodily harm if I do that.
