KonySo theres been a lot of talk in the media about Joseph Kony. He's not a good guy. This campaigning has been done by Invisible Children. It doesn't sound like they're good guys. I have yet to watch the documentary they created, but I have read multiple articles critisising it on many levels. If you're concerned about this issue, might I recommend you do the same?
I'd start with this metafilter thread, then maybe this, this and definitely these three links. Oh, and this. Then, if you feel like making a difference, this page has a lot of resources.
