I don’t know if you have heard of the Causes application on Facebook but CAIRN, a client for whom I am the community manager, is now listed there. One of the cool things that people can do with the Causes app is to talk to their friends about a charity work that is important to them (My Causes: Cairn, Kiva.org, Breast Cancer Research).
And now… you can choose to ask friends to donate to your favourite charity instead of buying you a birthday present. A brilliant idea.
