Steven Johnson was on the Daily Show, and I put the book on my list as a "future" read. I finally got around to reading it. I felt that the book had many valid points, and the comparisons between pop culture 30 years ago and today are interesting. Some of his theories and claims are unique, although most of it is not revolutionary. It reads almost like a textbook (in fact, I think I found the book in the science section of the bookstore) and is analytical in approach including graphs and charts to help convey his points. The book illustrates the merits of pop culture and even finds some hidden benefits in mediums that almost seem to be pure trash.
