The document discusses using social media for social good by engaging different levels of an audience pyramid. It outlines the characteristics, typical actions, and messages for the Community, Congregation, and Core levels of the pyramid. It also discusses using a two-pronged engagement strategy of "Heartbeats" for regular low-level engagement and "Remarkables" for inspiring remarkable actions. Remarkables are described as changing the medium or visualizing the message to spread on social media and engage more people. Working Heartbeats and Remarkables together can strengthen impact, relevance, and volunteer power for an organization's social good mission.
