You can select where you want your bitcoins to be used for.
I already select what my money is used for.
I think your goal is too broad to achieve. Can you give an example of how you can better deliver donors value to people who want to consume it than the donors themselves? Maybe you could find the people who can't manage on their own and let potential donors know about them.
Generally I see A--->ORGANIZATION--->B with ORGANIZATION not providing anything but a guess at what B wants (which B necessarily disagrees with or they would give money straight to B) and a bunch of heartwrenching commercials directed toward A. I bet if you find some kind of P2P solution a lot of people here would be interested, but I doubt another ORGANIZATION will get much traction.
Hope that's helpful.
