I've thought about doing this in the beginning, but decided against it because it would lead to a bias favoring both extremes on the beauty scale, with those in the middle receiving a lot less votes. That's because people would be more inclined to rate someone directly on their profile if they were either very beautiful or very -- how should I put it -- not-so-beautiful. Most users won't bother rating someone who is a 5 or a 6, so this would result in the users on the extreme ends of the scale (particularly the very beautiful ones) getting a disproportionate amount of votes.

By making it random -- and only random -- it ensures everyone gets the exact same opportunity for votes, regardless of how beautiful they are. Furthermore, most of the users you see in the search results are sorted by last login, meaning there would also be a disproportionate number of votes towards users who login frequently vs. those who do not, since less exposure, would mean less votes. Again, making it random resolves that issue, ensuring ALL users get an equal and fair chance of receiving votes.

Does that make sense?

@Andres: Yes it makes sense I did not think of those areas. It would be jacked up to find a site with the hots and not so's split right in half! Lol what a hard site that would be to manage!
