Ideas for philanthropic web services?
I've been brainstorming ideas on how to make a web service that can provide some degree of utility to people wanting to help others or people wanting to make this world a better place. I'm researching most of the current "donate to X charity"-type websites, such as yourcause.com, and am looking for ways that I feel they come up short. Perhaps I can pick up where they've dropped the ball. Most models for these sites are just about keeping you informed about these charities and helping you to donate money to them. I think a lot of them fail at showing you your impact when you do actually donate - so I'm thinking about targeting that side of it all.
Does anyone have any insight into this field, or any suggestions about things you've seen that could be helpful to somebody that just wants to "help out however they can"?
Thanks
