I'll keep this as brief as possible:
There's an excellent chance that the technology you're using to read this contains components built on the blood of innocent people in the Congo. In today's New York Times, Nicholas Kristof says the conflict is the most barbaric war he's ever seen (which is saying something) and "the most lethal conflict since World War II."
Please go read Kristof's piece.
At least go watch this video. It's funny. In a scary way.
And--if you're gonna be a consumer, please be a smart one. That's all I'm asking.
