Everyone knows how Chris Anderson's The Long Tail was written primarily online as a collaborative effort. So were Naked Conversations, by Robert Scoble and Shel Israel, and a few other books.
My next book happens to be about bloggers, and though there is some discussion of blogs turning into books in it, I'm not writing it online.
However, you can have a say in selecting the cover the next book, Blogging Heroes, to be published by Wiley this fall. Having discovered opinions are spilt almost evenly over the two possible covers for the book, publisher Joe Wikert is seeking reader input.
