Before I read this book I had no idea of what the "point" of blogging was all about. Sure, I knew the technical details, but the whole thing just didn't "congeal" in my mind and make any practical sense.
After reading this and a couple other books over my summer vacastion, now I get it! Finkelstein does a wonderful job of not only providing an introduction, but enough supporting material so that I knew what to do with it. If you'd like to figure it all out yourself, get this and the companion Buzz Marketing book and give them a read. Then join in the fun! Highly recommended.
