In this TED talk, How web video powers global innovation Chris Anderson shows how global innovation is being fueled by online video.
For a while now, I've known that each new book that I write must be accompanied by video. I thought of the video as a way to promote the book.
I now think I got it backwards. Online video may be the most important part of an intellectual project (like writing a book). The book itself may just be a 'souvenir', a small part of an intellectual project, a specific tool for researchers and text-oriented applications.
