http://shrtn.co http://shrtn.co (posted on HN very recently) has an interesting take to being charitable. They allow users to gain money by placing shortened affiliate links into their social posts. Another option is for users to donate any affiliate money they generate to charity. In this case, shrtn.co will add 20% of the money donated. In this way, you get to 1) do some good, 2) benefit from the marketing of it and 3) retain most of your profits. Seems like a damn good middle-ground to me.
