Years ago I remember when my then-professor, Larry Lessig, announced that he was hanging up the speaker's mic to concentrate on his research (and to give time back to his family). I pleaded that he would not abjure his freedom fighting. I asked who would take up the mantle in his absence?
Larry's answer was typical of him:You.
By which he didn't mean "me" per se, but rather those who looked to him to help promote open source, net neutrality, etc. Tim Wu of Columbia Law School has taken up that charge. Tim studied under Larry at Harvard and has been particularly involved in opening up the wireless world to competition, innovation, and capitalism. (Yes, you read that right - it's one of those ironic offshoots of freedom. It tends to lead to greater financial opportunities.)
