I share your opinion about most big charities. I understand they have staffing, cost, etc, and that part of the money that we donate has to go to keeping the costs covered; however, when I start looking at the actual percentage that makes it out to the people who I thought I was helping with my donation, I'm usually alarmed. It takes a lot of research to find a charity that I'm comfortable with, and those are usually local and small. Trying to help on a global scale usually finds me back in the hands of those super huge "nonprofit" organizations. Sigh. I do agree that Steemit has great potential to help people around the world, though if someone were to try and create a Steemit based charity to help more than just an individual, it could easily become similar to the charity organizations that we already see. I'm thinking that we'll never see a time when, as individuals, we can sidestep having to do due diligence on any organization or individual whom we wish to offer our help.
