This document discusses using social media for political campaigns and advocacy. It provides four examples: an Amnesty International Norway SMS campaign that engaged 80,000 people, Norway's Prime Minister Jens Stoltenberg's Facebook page which has 12,000 fans, advocacy blogs which need background information and a clear call to action, and the Atheist Bus campaign which was a simple yet effective social media campaign due to its quirky idea, celebrity backing, and low-cost WordPress website. The document advocates for integrating social media into an overall communication strategy and mobilizing online communities for offline action.
