True, but they already say that. I don't think that they stop showing you 'ugly' people, they just shift the distribution. In any case, the bottom 50% of users are probably cluttered with abandoned profiles, joke profiles, people with serious personality defects that can't get a date, et cetera. If you're an active serious user, you probably only have to be in the to 70-90% of active serious users to meet the criteria. We know they run statistics all the time from their blog, so they probably saw something like 90% of active users are in the top 50% and saw it as a way to flatter them and keep them engaged with the site.
