Back in the day, you used to have to go through the arduous task of going out into the world, talking to a member of the opposite sex to determine common interests, and then make a leap of faith to begin the dating process.

Social Actions takes actions posted on the web from more than forty different socially progressive organizations, and aggregates them into a common format for easy discovery. The actions are concrete activities like volunteering, donating, signing a petition, making a loan, or attending a meetup, all in the service of "making a difference" for issues like Darfur, cancer, LGBT, prison reform, and other activist concerns. On the Social Actions site interested citizens can search the opportunities, and an API (our Social Actions API profile) allows developers to build on top of the stream of postings.
