From Charles Petersen in the New York Review of Books:
Facebook, the most popular social networking Web site in the world, was founded in a Harvard dorm room in the winter of 2004. Like Microsoft, that other famous technology company started by a Harvard dropout, Facebook was not particularly original. A quarter-century earlier, Bill Gates, asked by IBM to provide the basic programming for its new personal computer, simply bought a program from another company and renamed it. Mark Zuckerberg, the primary founder of Facebook, who dropped out of college six months after starting the site, took most of his ideas from existing social networks such as Friendster and MySpace. But while Microsoft could as easily have originated at MIT or Caltech, it was no accident that Facebook came from Harvard.
What is “social networking”? For all the vagueness of the term, which now seems to encompass everything we do with other people online, it is usually associated with three basic activities: the creation of a personal Web page, or “profile,” that will serve as a surrogate home for the self; a trip to a kind of virtual agora, where, along with amusedly studying passersby, you can take a stroll through the ghost town of acquaintanceships past, looking up every person who’s crossed your path and whose name you can remember; and finally, a chance to remove the digital barrier and reveal yourself to the unsuspecting subjects of your gaze by, as we have learned to put it with the Internet’s peculiar eagerness for deforming our language, “friending” them, i.e., requesting that you be connected online in some way.

John Markoff reviews W. Brian Arthur’s The Nature of Technology in the New York Times,


e react, people think, and people remember. And you encounter this not only in a theoretical way, but when you meet people, when suddenly people start forgetting things, when suddenly people depend on their gadgets, and other stuff, to remember certain things. This is the beginning, its just an experience. But if you think about it and you think about your own behavior, you suddenly realize that something fundamental is going on. There is one comment on Edge which I love, which is in Daniel Dennett’s response to the 2007 annual question, in which he said that we have a population explosion of ideas, but not enough brains to cover them.
