The Berkman Center welcomes Doc Searls today in his new appointment as Berkman Fellow. Doc Searls is Senior Editor of Linux Journal, where he has covered the Internet, free software and open source movements for more than a decade. He is also (with fellow Berkman Fellow David Weinberger and others) a co-author of "The Cluetrain Manifesto," and is one of the world's most widely-read bloggers. Doc Searls on "The Giant Zero":"The metaphor is a play on the meaning of both World of Ends (which I co-wrote with fellow Berkman fellow David Weinberger) and The Stupid Network, by Berkman alumnus David Isenberg. (David is also my given name, by the way. Coincidence?) The origin of the metaphor, however, is Craig Burton, who was the first to observe that an end-to-end architecture in which every point is essentially zero distance from every other point (and as stupid as possible in the middle as well), would geometrically resemble a 3-D zero." Over the next hour, we'll hear Doc speaking at a Berkman Luncheon Series event on September 19, 2006. Video produced by Indigo and Colin Rhinesmith. VideoBerkman is a production of the Berkman Center for Internet & Society at Harvard Law School. Less
