I just completed Paul Gillin's new book on blogging success stories: The New Influencers : A Marketers Guide to New Social Media. Robert Scoble says that the book is an excellent followup of blogging success stories to his book, The Naked Conversation.
I agree, this book is a much more balanced than Scoble's Naked Conversations, while covering much the same territory. The concentration on specific influencers, and how they come to influence with this technology is a good orientation. Gillin takes much more of a marketing view of the subject. He includes some negative examples where blogging was misused. He also has the advantage of being a year later, with more up-to-date examples, and covers podcasting in more detail as well. He addresses the use of wikis, but I wish he had addressed the issue of engaging people to contribute wikis as well as other social media. This is not a how-to book, but an argument why you should consider using blogging and related technologies. I see it as a good replacement for previous general books on the subject. No coverage of internal blogging. The book's site has some bonus material. See also Paul Gillin's blog.
