I wish I had time to put together a well-crafted post on Wikileaks, but I don't. RW's is quite good, though, and I don't find much there with which I disagree.
So I'll just get to the point. I think Julian Assange is a badass, and in my more optimistic visions of the future, his name is mentioned in the same breath as Gutenberg's. I'm probably overstating the importance of Wikileaks qua Wikileaks, here...but I do think we are seeing the beginning of a fundamental shift in the ability of institutions to maintain their hold on power by controlling information.
Whether or not you think this is a good thing...it's hard to avoid the notion that the future belongs to those who can adapt to this reality.
