I'm no Oprah, but here's a book I can recommend whole-heartedly. And that without having even read it yet (downloading as we speak).
Admittedly, I'm a fan of Prof. Lessig's ideas, as is a growing legion of people who have discovered the benefits of licensing their work under Creative Commons licenses.
I had the privilege to meet Prof. Lessig at the iSummit held in Sapporo, Japan last year. On the spur of the moment, I presented an idea regarding CC+ licenses and a sample marketplace on ccmixter.org – it was generally considered a good idea by those in attendance, and though it's not been implemented, I'm happy I threw the idea out there and maybe someone will act on it in the future.
I need this book. Please send me this file.
