This document discusses lessons for e-democracy from two case studies: WikiLeaks and the 2011 Queensland floods in Australia. It finds that both events saw rapid self-organization and participation on social media to share information. Communities developed ad hoc structures and innovated with new tools. Authorities were able to engage more effectively by meeting people on their platforms rather than imposing new ones. Overall, e-democracy initiatives should lower barriers to participation, distribute across multiple platforms, allow organic community development, and view ongoing events as opportunities for engagement.
