1. The Library Foundation of Los Angeles, which raises funds for important programs at the library such as summer reading and adult literacy. They run the ALOUD series of author events (I recently got to see Patti Smith!) and operate a sweet nerdy gift shop downtown at the Central Library. http://lfla.org
  2. (RED), which raises money for the Global Fund to fight AIDS in Africa. http://red.org
  3. Medicins San Frontieres, or Doctors Without Borders, because they're on the front lines of every major crisis. http://msf.org
