For a site whose key value proposition is vanity - is it really? HotOrNot scales all ratings by (rating / 2 + 5.0), i.e. everybody's above average. According to the post by James Hong where he mentioned this, they seem to have found a notable increase in user satisfaction with the change.

Is it any different from Victoria Secret bras running a cup size or three higher than everyone else, or dress sizes continually shifting downwards, or SAT scores being recentered upwards by 100 points?
