I am a fan of online dating, especially for those who are out of school. There is just no other way to interview so many available candidates efficiently, with the advantage of screening them in advance.
When people get divorced, I usually recommend that a person have a coffee with at least 25-30 candidates, at minimum, before deciding to get involved with anyone. That's because the recently-divorced are usually lonely, unhappy, sex-starved; often hurt or angry or worried about the future, and generally prone to poor judgement and poor choices. However, those things may apply to many single people.
Because of this, I found this fellow's love story interesting: How a Math Genius Hacked OkCupid to Find True Love
Do guys just want sex? That's a topic for another day. That guy wanted true love, whatever that is.
