Shel Israel & Robert Scoble have written a book called "Naked Conversations". It was an unique experiment were they talked about the process of writing the book. I haven't read the book (it is not released yet), but I guess it is all about "how blogging has changed the rules of communication and competition".
In 2005 and 2006 a huge ammount of books will be released all about: weblogging and business. Most of these books will talk about weblogging from a sender point of view. Why can't we change the perspective? Why must we (i've just started blogging in 2003) always talk about the sender and the technique of blogging? Why not take a look at the readers of all these blogs and listen to their needs?
