In their words:

You've probably heard of the Six Degrees concept. Any one person is connected to any other person through six or fewer relationships, because it's a small world. SixDegrees.org is about using this idea to accomplish something good. It's social networking with a social conscience. Through this web site, you can support your favorite charities by donating or creating fundraising badges — as well as check out the favorite causes of other people, including celebrities.

www.SixDegrees.org was started with the nonprofit Network for Good in January 2007, more than 10 years after the game, "Six Degrees of Kevin Bacon" made the rounds of college campuses and lived on to be a shorthand term for the small world phenomenon.
