I do not know it this is true but according to people he worked with everything was done via email. They did not met the person. If you check there are messages on this forum from satshi himself. One thing is for sure whoever Satoshi is he is a genius and now a very wealthy man.

It would make sense if satoshi nakamoto also establish this website bitcointalk since as I have heard, this site started with a few members only discussing bitcoin like an organization. Only satoshi could rally people explaining something very trivial like a cryptocurrency in that early period of internet. He's identitiy is yet to be know but he/they is definitely exhibit a genius mind and skills in programming and marketing to be able to create something this successful.
