Steven Johnson on Big Business Semiotics

Here's a lecture Steven Johnson gave last night at Columbia about the future of text. (Steven has a transcript here.) Lo and behold, that degree in semiotics twenty years ago makes a lot of sense now! [Update: I embedded the video here this morning, but it starts on its own, and sometimes it shows a lecture by someone else. Future of journalism, indeed--c'mon, Columbia! Here's the place where I think you can find the video.]
