Now you too can
express social outrage

Online social activist group Project Agape will launch a limited version tool on Facebook, according to GigaOM.

Dubbed Causes for Facebook, it integrate into the social network and allow users to build and grow a cause through viral invites. Causes can then call upon members for monetary support.

Project Agape is just one of the developers let in Facebook's back door as it tries to build a Social OS. Other developers, like mobile startup Tiny Pictures, are also embracing the opportunity to reach the 23 million-strong community.

The Internet and social causes have been consistent bedfellows since broadband penetration began to climb. According to Pew Research, 52 million Americans use the Web to research policy issues and 38 million have sent an email to government officials trying to change policies.
