What's wrong with all those dating sites?
dusklight: The biggest problem is that the incentive of the dating site is to make money, not to help people get together. If your service is really good at getting people together, boom! There goes your userbase as they all hook up and log off.Financially speaking it is better to give users the ILLUSION of someone out there being for you, while stringing them along and milking them for as much cash as possible.
