Kiva

Kiva.org is a micro-lending site. What a concept! From their site:

Kiva's mission is to connect people through lending for the sake of alleviating poverty.

Kiva is the world's first person-to-person micro-lending website, empowering individuals to lend directly to unique entrepreneurs around the globe.

The people you see on Kiva's site are real individuals in need of funding - not marketing material. When you browse entrepreneurs' profiles on the site, choose someone to lend to, and then make a loan, you are helping a real person make great strides towards economic independence and improve life for themselves, their family, and their community. Throughout the course of the loan (usually 6-12 months), you can receive email journal updates and track repayments. Then, when you get your loan money back, you can relend to someone else in need.

Wow. Here's how it works:

Choose an Entrepreneur, Lend, Get Repaid

1) Lenders like you browse profiles of entrepreneurs in need, and choose someone to lend to. When they lend, using PayPal or their credit cards, Kiva collects the funds and then passes them along to one of our microfinance partners worldwide.

2) Kiva's microfinance partners distribute the loan funds to the selected entrepreneur. Often, our partners also provide training and other assistance to maximize the entrepreneur's chances of success.

3) Over time, the entrepreneur repays their loan. Repayment and other updates are posted on Kiva and emailed to lenders who wish to receive them.

4) When lenders get their money back, they can re-lend to someone else in need, donate their funds to Kiva (to cover operational expenses), or withdraw their funds.

Can you think of a better way to use part of your tax refund? I can't.
