Social Actions is an open source database of actions people can take on any issue. The actions in our database are aggregated from across the social web and include everything from volunteer opportunities to micro credit loans.

We encourage social tech programmers to develop web applications that intelligently distribute the actions in our database across the websites, social networks, and mobile phones that millions of people use every day. The overarching goal of our work is to make the web more action-oriented, or in other words, to make it easier for people to make a difference.
