Shameless plug, but related, is the Watsi platform[1] I discovered a few months ago through another HN user. You can read the story of less fortunate but alive people and how much need there is in the world for one another. The founder's talk[2], Chase Adam, which made me a supporter, is a must-see. I guess it's time to rewatch it..
