I just went to a party, and on the invitation I was confronted with the "your presence is present enough" line, meaning no gifts. However, in situations like this, I always bring a gift, because God-forbid I'm the only one who actually listens. But on this invitation, it said if you still want to buy something for the host, you could buy a gift certificate to Kiva. org, which I knew nothing about. So I did some investigating.
It turns out Kiva is a micro-lending site, that lets you "lend money to a specific entrepreneur in the developing world -- empowering them to lift themselves out of poverty." Already interesting, I thought.
