I'm vaguely considering trying one (probably in the same way I consider doing a lot of things I know full well I'm not actually going to do) but am not sure which ones are actually quite good. I looked at Match.com once but everyone there seemed a bit bland and middle-of-the-road (not that I'm after anyone hugely weird but somewhere intelligent, amusing people who don't take themselves hugely seriously'd be nice)

Are there any decent sites out there?
