OK Cupid, the hetero dating site, keeps crunching numbers about their members and blogging them. It's pure stats-porn for numbers geeks like me.

However, the distribution of e-mails to men from the women basically follows that distribution curve—that is, about 80% of the e-mails go to the below-average men. On the other hand, two thirds of e-mail sent from men to women go to the top one-third of women, appearance-wise. Women are pessimistic about men, but realistic in their aspirations. Men are realistic about women, but optimistic in their aspirations.
