Charlie--Lessig Reaction

I couldn't watch the whole video because my internet was giving me problems, but let me just start off by saying that I think Lessig is one of the greatest presenters I've ever seen. My junior year history teacher loved him and modeled his presentation style off of Lessig. Lessig's method of using mostly pictures and minimal words is really creative and one that a lot of my professors at Brown could learn from. The issues that he brings up reminds me a lot of "The Social Network" and the issues in the creation of Facebook. Can somebody own an idea? Where does the law have jurisdiction when the human mind comes into play?     I think the public should have a more active say in what power the law has.
