This should be required reading for any digital rights activist. Although Lessig is ocassionaly quit the American lawyer he manages to make a set of important arguments with a clarity of thought that I haven't encountered elsewhere in the thinking on intellectual property, privacy and free speech.

He argues compellingly that "Code Is Law" and the way he makes explicit what "things" regulate (law, norms, market an architecture) is an incredibly valuable tool for framing future discussions about these difficult topics.
