but broadly "writes with acuity and passion". Lawrence Lessig, who was criticized in both the original essay and in the book, wrote an extremely negative review of the book in which he listed what he stated were a multitude of errors in the book including mischaracterizations of Lessig's views and work. Lessig also set up a wiki where users could collaborate in listing problems with the book. Larry Sanger, co-founder of Wikipedia and founder of the expert-centered wiki Citizendium, gave the book a mixed review. Sanger said that "The book is provocative, but its argument is unfortunately weakened by the fact that Keen is so over-the-top and presents more of a caricature of a position than carefully reasoned discourse." He said that it was hypocritical for Keen to express support for Citizendium, for incorporating expert opinion, when the inherent point of the project is to supply free content, which Keen so opposes in principle. Sanger stated that the book "combines several different criticisms of Web 2.0, incoherently, under the rubric of 'the cult of the amateur'" but the book "is a much-needed Web 2.0 reality check". Tim O'Reilly commented in response to the book, "I find, Andrew Keen's, his whole pitch, I think he was just pure and simple looking for an angle, to create some controversy and sell a book, I don't think there's any substance whatever to his rants." Furthermore, he has said in response to the book, "I think the Internet is often held to another standard. You don't say, 'Why aren't the newspapers writing about Bismarck, he is more important than Pamela Anderson.' But people will say that about Wikipedia. It's just bias." Anthony Trewavas, professor at the Institute of Molecular Plant Science at the University of Edinburgh, discussed the book in an article in Trends in Biotechnology. Trewavas wrote that Keen's "concern is the blurring of the distinction between the qualified and informed professional and the uninformed and unqualified amateur", expressing concerns that this social change can hold back agricultural development. Trewavas stated as well, "in agriculture, pesticides, food and farming, expert scientific knowledge and experience is seemingly regarded as having no more weight than that of the opinionated, unqualified (and inexperienced) environmentalist." The book has also been discussed in academic publications negatively, expressing how Keen has considered the worst aspects of a complex social movement while ignoring the demonstrable benefits that have been brought
