It tweeted my intent. Though I donate regularly, I don't think people need to share every time they donate. So why did I do it? I want to set an example and it have it as a call to arms for people to do the same. 

I got to thinking that if people spent as much effort tracking donations and giving of free time as they do where they eat and play (FourSquare, Gowalla) then perhaps people would be motivated to donate more often. I certainly don't think people don't donate due to lack of funds or good intentions. Sometimes it's a matter of getting around to it. Receiving achievements (either privately or posted on facebook) such as "Mark achieved the Susan G Bronze" for donating three times to Susan G Komen For The Cure, or "Steve Received +5 points for first donation to The YMCA." ThreeSquare.com might be a good name (taken).

Another motivator may be the online action of a group to achieve a result in a certain timeframe. People already do this TeamInTraining, Aids Run and Walk, grassroots organizations that sell Tupperware and decide where to donate proceeds. If such a theme of collectively achieving goals could be applied to social media, the results could be huge. The snowball affect would be huge as more people jumped on the online bandwagon.

Some of this has been done before. I still think it might be fun and rewarding to build a site that combines the achievement system of Xbox Live, FourSquare with "Crowdphanthropy" to meet a short term fundraising goal that is determined by the users.

Cheers, Mark
