This document discusses prototypes for encouraging civic engagement through collective action using mobile technologies. It describes two initial prototypes: having people share ideas with strangers for a reward, and sharing ideas to help the community. Lessons learned stressed focusing on a specific issue or community, clear directions, incentives, and engagement. Further prototypes were proposed to re-imagine neighborhoods and collect/share local information. The overall goal is to empower citizens and youth to advocate for their communities through collaborative technology.
