This sounds like it shouldn't work:

- If it starts showing you to unusually attractive people wont those people rate you unusually low until you reach some equilibrium?

- I would expect any feature determining the top most attractive should use a weighting of the raters (like PageRank)

- I would expect OKC to try to be optimizing for total matches: that means they should have some system for "you rate a certain cluster of people unusually high, we should direct you to that set of people since the other people you rate high are already saturated"
