In part 1 of this 3 part series, we were at the Snoball party. Snoball is a company that helps non-profits get funding. Their model is simple: sign up, set up a declaration, and give money.
For instance, you can set up a trigger that states every time you eat at a certain place, your favorite non-profit gets $5 (or whatever you want to set). Have 100 people check in to Foursquare, donate money to a worthy cause.
