Lessig's Code v2

Although slightly annoying to me personally with his compromising attitudes, Lessig still plays an important role. Reading FSF's member forums someone linked to some article on Lessig.org where I noticed a new book being advertised: http://codev2.cc/

It's the second revision of Lessig's book "Code". Might be worth a read. It's not been authored by Lessig alone, as it was on a wiki for quite a while when others were able to edit it as well.
