Pablo sez, "Kiva.org is the world’s first peer-to-peer, distributed microloan website. A great idea where PayPal meets Gates Foundation. The site allows you to lend a small amount of money, say $25, to needy microenterprises in developing countries. You receive repayment at the end of the loan period (normally 6-12 months) without interest. If they default on the loan, your loan becomes a donation – though none of the businesses have defaulted yet. A great low-risk, high-reward idea."

(Thanks, Pablo!)
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
