I'm a big fan of Kiva, a web site where you can lend small amounts of money to hard working entrepreneurs in developing nations.
My experience has been very good so far; all of the money I've loaned has either been paid back completely or is getting close. Most people recycle the money that's paid back, which is what I intend to do in the next couple of weeks.
If you're interested, check out my Kiva loan portfolio. I encourage you to try Kiva too!
