I had a great conversation with on of my co-workers about this website that allows you to loan small amounts of money to people to start businesses. http://www.kiva.org/
My co-worker was inspired by the creator of this company to go to grad school pursuing these ideas.
You see profiles of people who need money from a rice farmer in Nepal to a prospective cafe owner in Portland. And you get the $$$ back in a year! How cool. I have no money to loan right now, but I love this concept!
