Don't believe matchmaking websites:
[A]s it stands now, online dating sites can pretty much claim whatever they want without fear of retribution. The "scientific" algorithm behind eharmony, for example, has never been tested against other algorithms to measure whether or not it makes any difference in the quality of relationships experienced by users. Basically, you might be better off just going to a bar and introducing yourself to a bunch of dudes who don't appear to have girlfriends. Or just playing World of Warcraft for awhile. Or just go onto OKCupid and find someone with a weird tattoo, for free.
