I have read a lot about this and done a lot of digging around to try and see whom I think Satoshi is or was.  I think there are two trains of thought, either Satoshi did a lot of things on purpose to throw people off, or there were a couple individuals who made up Satoshi.  I know Satoshi once used the term "bloody" as in like "bloody hell".  As an American I can tell you we never use that term here. So it makes you wonder.  Personally I think that it was a combo of cypherpunks such as Hal Finney and Nick Szabo.
