At this point, Wikileaks appears to be a big and interesting idea (transparency for all information can make the world a better place?) poorly executed. Founder Julian Assange was careless at best when he released the names of Afghan civilians helping the fight against the Taliban--putting their lives in great danger. A cynic might think Assange rushed to publish the documents to maximize his personal prestige, particularly since he has since asked for help in editing the now public documents (why not ask for help ex-ante?). Assange's apparent anger toward human rights organizations also seems misplaced http://online.wsj.com/article/SB****************************558.html?mod=WSJ_hpp_MIDDLENexttoWhatsNewsTop
The site does contain a tremendous amount of interesting information not just on the Afghan war. However, I do believe it should all be read with a grain of salt because much of the information lacks the context needed to truly understand it. Net net, I believe Wikileaks to be an interesting project that I hope will actually make the world a better place. But for now, I really think it's a wait and see.
