Larry Lessig and Andrew Keen debate

One issue I've found with Andrew Keen is that he has a very difficult time supporting the ideas that he writes about in a verbal confrontation. When people attack him and his ideas on Web 2.0 (as Larry Lessig clearly is) he seems uncomfortable and even comes across as unintelligent sometimes. However, in his actual writings he is fiery and passionate. It makes me wonder if his strength isn't simply in writing very prettily; his words on the page are very convincing, yet watching interviews and debates I find myself wondering how I ever believed him.
