Just recently I was imagining a dating site that doesn't use personal profiles, just randomly matches people with compatible age and gender settings (weighted by proximity and how long they have waited for a match) and trying to think through how it might work.

There would have to be a penalty for rejecting a match before setting up a date or for cancelling on them, such as a delay before being able to request another match (and maybe double the delay each consecutive time)

Anyway this would eliminate the whole '5% of men get 90% of dates' thing (whatever the real numbers are) - after requesting a match eventually everyone would get one. There would of course have to be a report system for actual problem people. And likely straight women would get dates much faster (more frequently) than straight men, but still more evenly distributed.
