The document discusses strategies for building successful social movements and engagement campaigns. It provides examples from Obama's 2008 and 2012 campaigns, which achieved massive email lists and fundraising. Other examples discussed include the It Gets Better project against LGBT bullying and corporate brand examples from Ford Motor Company. The key lessons are to seize pivotal moments, listen to supporters, integrate online and offline channels, and focus campaigns around clear objectives rather than just pursuing a "viral" or "movement" label. Proper segmentation and targeting of supporter groups from interested to advocates to evangelists is also emphasized.
