This is a very convincing argument that copyright laws as they stand are not doing the job. Anyone interested in this issue should at least give this a skim. Lessig's writing style, full of unfunny asides, can get annoying and there are some obvious editing mistakes that I can't believe weren't caught. There are also (as is typical in business books) way too many examples and not enough content binding them together. In sum, I'd say read the opening, skim the middle pages and tune back in for the conclusion.
