The top 10 feature didn't indicate a 'more compatible' person when i was dating a few months ago. One 3 date stretch, one absolute misfire (no second date at all) and it also kept repeatedly recommending (top prospect HA) a total asshat that screwed me over a couple of years ago.
mildly amusing though that POF was so convinced he was my best prospect!
There should be a feature that removes people from the best matches list, there are girls in that list that I've met and they never led to anything and there's no way the site would know which chicks are disastrous vs those who aren't. Maybe a rating feature or something.
