Cory Doctorow has a multitude of talents. He's a co-editor of BoingBoing, the fifth most popular blog on the Internet according to Technorati, where he purveys a mixture of technology news, links to strange and wonderful things, and left wing politics. He's been a front line fighter in the wars over intellectual property; he used to be the Electronic Frontier Foundation's Director of European Affairs.
Chait has, in the past, been blisteringly rude about the netroots (some of whom have also been blisteringly rude about him).

However, it would be a serious mistake for netroots readers to ignore this book, or think that it has nothing to teach them.
