how do you know that was Satoshi who wrote that, I can make a better picture than the one above and sign it with his name, also everything on that story fits perfectly to that man, I am almost convinced that is him...
and by the way, he used his real name, nice move last thing expected....
A big piece of evidence that's missing is a link between this guy and crypto mailing lists. The real Satoshi was heavily influenced by cryptographers that went before him so I would have though it highly likely that he would be a subscriber to these lists.
