In her new book, Momentum: Igniting Social Change in the Connected Age, Alison Fine stands at the intersection of new technology on community activism.

Fine takes the skeptical community activist, nonprofit communications manager, or policy advocate on a whirlwind tour of new social media. She peeks in at everything from blogging to on-line advocacy and everything in between. She provides accessible examples of grass roots campaigns qualitatively reshaping and enriching themselves through judicious use of new web technologies.
