New Book on Web 2.0

A must read book. The author has explained the Web 2.0 philosophy in a very intuitive way. He talks about how to monetize the websites at the same time attract the users by giving them
some free services. He calls this as Freemium.
The book discusses the success stories of Flickr, Facebook,Linkedin, google. The basis of all the success story is the rich user base.All of them have followed the long trail concept by reaching out to the masses rather than concentrating to a niche segment " Every buck counts".
Since the book talks about the sites which we commonly use it is easy to realize the concepts since we are the part of the revolution happening around the particular site.

I would highly recommend this book to anybody who wants to find out what is this web 2.0 business all about.
