For me, this book was really kind of rudimentary, but it is an excellent introduction to social media (think Goodreads, Twitter, Facebook, blogs, etc) and how they can shape and be shaped by emergency and disaster situations.
This text provides some good examples of successful communication strategies, as well as suggestions on how to improve existing communication plans. This should be "must read" for anyone in emergency or disaster management (EDM), no matter what their level of responsibility. Especially, this should be high on the list for anyone in EDM leadership, as well as local government leadership. The suggestions provided are well presented and thought out.
