Seconded. Great site.

I haven't used any other dating sites, so I have no proper basis for comparison, but I've been very satisfied with the site, from matching system, search options, etc.

Bottom line: I ended up meeting my current girlfriend there and things are going very, very well with her. Anecdotal evidence, yes, but I hope it complements the nuggets of awesomeness you'll find on OKTrends (http://blog.okcupid.com).
