My friend Dave introduced me to the concept of microcredit/microfinance through this incredible book:

I'm in the process of reading them now.
Before I had heard of microcredit, I had come up with an idea that I dubbed Atlas Smiled. I've posted the idea up on Omidyar.net here:

Dave had also organized an awareness dinner with Unitus, which sounds like an incredible company.
