At the book store the other day I stumbled on Cory Doctrow's recent book "Content." It's a collection of his essays regarding intellectual
property. I went to his website (the back of the book said Doctrow practiced what he preached and put his writings online) and found that
in addition to a pdf version of the book, he also posted an audio copy. I just downloaded it and look forward to listening to them.
Though some of you might want to check it out too:
