It feels important to remind ourselves, at this point, that Facebook, our new beloved interface with reality, was designed by a Harvard sophomore with a Harvard sophomore’s preoccupations. What is your relationship status? (Choose one. There can be only one answer. People need to know.) Do you have a “life”? (Prove it. Post pictures.) Do you like the right sort of things? (Make a list. Things to like will include: movies, music, books and television, but not architecture, ideas, or plants.) But here I fear I am becoming nostalgic. I am dreaming of a Web that caters to a kind of person who no longer exists. A private person, a person who is a mystery, to the world and—which is more important—to herself. Person as mystery: this idea of personhood is certainly changing, perhaps has already changed.
