Donorschoose.org is a domestic charity that allows people to fund projects designed by US public school teachers. It is a great initiative, started by teachers but expanded with funding from several successful internet entrepreneurs, and offers donors a lot of information before they give as well as information on project implemention. The format is a lot like Sean Stannard Stockton suggested was the future of philanthropy.
The site's directors recently gave what looks like it was a very poorly attended presentation at Google Tech Talks. It is almost an hour long, but does a great job explaining how it all works.
