Something that always made me think Satoshi was American was his use of the American English spelling of certain words. Your emails show an example like American spelling Organization instead of the British spelling Organisation. But the Genesis block British headline threw me off. Back in the day I just figured he was an American living in England. But I didn't really care. Back then, nor today, did I use my real name on any internet correspondence that wasn't work or finance related. I was compartmentalizing or practicing separation of concerns since I got on the internet in the early 90s and just thought everyone else did as well. My only regret was treating bitcoin as an IT curiosity early 2011 instead of taking it seriously.
