For me the Devil is in the behavior. Why would Satoshi go about proving his existence and identity is such a convoluted matter? Simply signing the genesis with a message and posting it pretty much anywhere (bitcointalk, /r/bitcoin, here) for people to verify is all it takes. Not a rambling blot posts full of screenshots and some back-alley interview. This is exactly the kind of 'slight of hand' that a conman utilizes, not a cryptographer of Satoshi's caliber.
