The document discusses how social media is changing the role of emergency management and public information officers (PIOs) by allowing everyone to be a potential "first informer". It provides examples from incidents like the Virginia Tech shooting and California wildfires where social media allowed faster and more accurate information sharing than traditional media. The document advocates for governments and PIOs to actively engage on social media platforms and integrate social media information into emergency response plans to stay relevant in an age where everyone can potentially be a first informer.
