I vividly remember first hearing about this book when it was discussed on NPR's Talk of the Nation. As part of the radio program, they examined the impacts of the web as a user-generated network and introduced the idea of customers as "prosumers" who co-create value along with the company--blurring the gap between producers and consumers. I immediately connected this to the idea of 21st century literacy and how our students are emerging into a world where, with Web 2.0 tools, they can produce content on the web just as easily as they can consume it, and they can essentially do both at once.
