Nick O’Neill at AllFacebook makes a great point: Facebook is having some growing pains when defining the relationships of its users. When you add a friend, you say “how you met them.” Right now, the options are strongly college oriented.

It prompts a big question: how strong should the lines on the social graph be?

Facebook has the tricky job of pushing users to create content while, at the same time, allowing this content to reflect the minutiae of interaction. If the friend connection was a blank space to fill in, the variance in answers would make the feature useless, and many users would come up blank without a prompt. At present, the prompt falls short of the different ways people come together.

How can Facebook fix the problem? Maybe it would be possible to rank friend meetings by other friend meetings. So, for example, if John the businessman has never “hooked up” with one of his executive contacts, that option would be pushed to the bottom in favor of more businesslike ones (like, “we met at a conference”). Meanwhile, if Sally is “hooking up” all the time….well, we’ll let Facebook work out the kinks for the options Sally would get.
