Of course, Lessig has a blog

For anyone who's looking for a little more information on Lawrence Lessig, I'd recommend checking out his blog at: http://www.lessig.org/blog/. It's a pretty general treatment of Internet issues, with a lot of focus on new developments on the Internet and open-access topics such as Creative Commons licensing and net neutrality.

And in case "Code" isn't enough, Lessig is currently in the process of working on the page proofs for "Code - Version 2.0"
