One more Wikileaks thought: how do they ensure that the stuff they present is correct? If I were a highly placed Wikileaks hater, I'd just have somebody leak them lots of false stuff, so I could call them on it and reduce the credibility of all their disclosures. Why wouldn't this work? Looking at the information on Wikipedia about how they verify things doesn't tell me much about how they can rule out false disclosures.
Update: Or if I was more a propagandizer than a hater, I'd just send my own juicy propaganda into Wikileaks and confirm it when it came out. If it was juicy enough, it'd become the real story and the media would ignore any other stuff that was detrimental to me.
