Facebook announces a new feature called Donate which makes it possible for anybody to give back to a charity of their choice through its Facebook Page.
Donate is the fortuity of a Hackathon project run by a Facebook team. As Facebook started to test Donate, its team have hooked up with a few nonprofits that have been using Facebook to engage supporters and promote advocacy such as World Wildlife Fund, World Food Program USA, and United Way among many others.
