Kiva specializes in micro-lending, a new trend in helping others in third-world countries. For twenty-five bucks, you can become a venture capitalist, lending money to people starting businesses all over the world. Among other things, I have helped finance a bar in Ghana, Africa, a taro farm in Samoa in the South Pacific, and a coffee shop in Bulgaria. The cool thing is that when they pay me back (interest free), I can pull my money out or reinvest in another business.
My portfolio now contains 19 businesses and I usually add another about once a month. Fun stuff. Check it out when you get a chance.
