I missed this announcement that Lessig made last month. He's decided to shift his energy to battling "Corruption" in public policy. As many of you know, Lessig was the first recipient of the Cyberspace Law Excellence Award given out by the Cyberspace Law Committee. I'm personally sad to see him move on to other issues, but his reasons (as usual) are unassailable.
You can read his announcement, entitled "The Next Ten Years" is here.
