There’s no way to take a time-out from our social life and describe it to a computer without social consequences. At the very least, the fact that I have an exquisitely maintained and categorized contact list telegraphs the fact that I’m the kind of schlub who would spend hours gardening a contact list, instead of going out and being an awesome guy. The social graph wants to turn us back into third graders, laboriously spelling out just who is our fifth-best-friend. But there’s a reason we stopped doing that kind of thing in third grade!
