Many of you are familiar with dust up between Chris Anderson and Malcolm Gladwell that was touched off by Malcolm's review of Chris's new book, Free: The Future of Radical Price. [UPDATE: Free is no longer free. The link to Chris's book has been retired. You can find Chris's book on Amazon.]
Anderson's book points out that the cost of providing web services is declining as a result of open source software, commodity hardware, and cheap bandwidth. Gladwell agrees with the trend but notes that it is very expensive for YouTube to host video.
