PledgeBank

PledgeBank is a website which runs pledges on all topics, of the form: "I will do x if y number of people agree to do the same." Such public commitments are a non-coercive way to solve problems of collective action, especially when the goal is a public good. PledgeBank was founded by mySociety and went live June 13, 2005. Though hosted/run by a UK-based nonprofit, PledgeBank has been translated by volunteers into 12 languages in addition to English. The Omidyar Network has funded outreach efforts for PledgeBank in the U.S.
