[N]ow [Orkut has] added this linear scale of friendship that would be laughed out of a freshman sociology course, and then they say tell me the data is private. Of course it's not private -- that data isn't for me, it's for Orkut. I don't need it in the first place, because I am a monkey, descended from a long line of such monkeys, whose main talent consists of keeping track of relationships. Measured on the time scale of our social capacity, fire is a recent invention and agriculture is still a novelty.Link
The "how good a friend are they" data is useless or worse for me, but useful for Orkut, because they are desperate to represent social networks numerically, which is why they keep adding things to an interface they should be subtracting things from. The problem isn't the cost or refinement of accepting a friendship transaction, the problem is that friendship isn't a transaction, something almost no social networking service understands.
