And the folks over at Invisible Children have posted a response to some of the concerns that have been raised over their charity. A very good read that addresses a lot of the issues. As I said, before you donate (to any charity), make sure you always collect as much data as possible so that you can make an informed decision.
Either way, I think that they’ve done a good job bringing an issue to light in a way that has definitely raised awareness. Even if there’s nothing direct we can do about a situation, it never hurts to be more educated and informed about the world around us.
