Very interesting...
If Mark Karpelès registered bitcoins.org on 3/30/2000, has coding experience as his LinkedIn proves, and lives in Japan (whence the pseudonym), I think it's a match as to him being Satoshi Nakamoto!
EDIT: might be helpful to rearrange your list of websites by date, from oldest to youngest

maybe
bold or
italicize names that are related (ex. Jennifer Dromon or Mark Karpelès appearing multiple times)
