Leave it to the desperate and horny to turn a social networking site, originally intended for recent college grads and underclassmen, into a meat market. There’s nothing wrong with liking someone and hitting up their profile to see if they are single, employed, and the like. Assuming the person is your Facebook friend, you should already know this about them. When it turns into obsession, though, the whole point gets lost. People forget that these sites were meant for socializing, not hunting.
