For years, I've donated to the standard large charities - Habitat for Humanity, Doctors Without Borders, American Red Cross, etc.
I'd like to find out what other initiatives do you know about, and why do you think they're worth donating to. I want to keep helping, but I want more "bang for the buck" - maybe actually notice some real change directly as a result of my contribution.
Charity Watch is a good place to check: https://www.charitywatch.org/home
