Alexander Dietz, a PhD student at the University of Southern California, kindly calls to my attention this initiative.  As I told Mr. Dietz, I am a bit skeptical of undertakings like this, for the simple reason that most human misery has systemic causes, which charity never addresses, but which political change can address; ergo, all money and effort should go towards systemic and political reform.  Mr. Dietz tells me that this project does not rule out donations in support of political change.
