Twitter: A Cultural Guidebook

This book does a great job of taming the sometimes intimidating beast that is Twitter. It breaks down the various aspects of the "how" and "why" people use Twitter. The authors have done a good job of incorporating many voices through the use of embedded video. I've loaded this book on all staff iPads as I feel it's a valuable resource and very well could be a catalyst that enables teachers to take control of their professional development.
