My friend Archon Fung and others have built “Participedia,” an online archive of articles about public participation and democratic innovation around the world. It’s wiki-style, so anyone can add cases and edit the ones that are there already. The site says:

Participedia collects narratives and data about any kind of process or organization that has democratic potentials. A process is democratic when it functions to include, empower, or give voice to those affected by collective decisions in making those decisions. That is, the Participedia understanding of “democracy” is broad, and does not prejudge where these processes might be found, how they might be organized, or who might create them.

The site already contains main important examples. They are looking for failures, too, which is very important because we tend to collect examples of success even if the odds of replication are poor. Smart strategic planning requires learning from mistakes.
