Free as a business model. Very cool concept. I love this book. This gives an insights on some companies I didn't know details about. Jeff Jarvis, the author of the book is a very credible person to write a book of this magnitude. He takes all the industries and puts Google in charge and shows what is possible if Google guys ran companies in any of the industries.
I have a few sites of my own such as Fortune Cookie Quotes and Stamps Book and I have a few ideas on how to make money by offering content for free. Currently, I have no money generating ideas, however, by offering GOOD free content, I believe I'll have a shot at making money in the future.
If you are into search engine marketing or in tech world in general, this book is for you. I read THE GOOGLE STORY, which was an excellent book as well. This book is just as good. I highly Recommend it.
