Recently I came across the website www.kiva.org - which happened to be an Internet based charity. What they do? They connect those people who need a microfinance with those small scale donors previously not accessible. It brings together people willing to lend a 25 $ with those who need a 500 $ for a cow, and syndicates it with different lenders globally. A fascinating technology, showing where you contribute and could make difference.
My belief is, that this peer to peer concept using institutional infrastructure for distribution but relying on a high number of small donors, has a great future. People have confidence to make a difference.
Have a look and think about, how this platform could be used in other ways as well!
