I just sent another contribution to Partners in Health so I thought I'd nag y'all a bit.
Here are a couple of links to people who have said it better:
Paul Farmer's testimony to U.S. Senate
Farmer was on the ground in Haiti years before this crisis. I've tried to talk up PIH without seeming like a shill. I just prefer donating to people who are helping Haitians help themselves.
James Rucker (colorofchange.org) post at JJP
I know James Rucker's mama and I know Van Jones co-founded his organization so I'm biased. But I like what he's doing to support Haitian relief efforts and how he expresses it.
