Interesting! However, they forgot to include the date when Satoshi Nakamoto introduced bitcointalk.org. It's empty on November 22.
Did Satoshi actually introduced bitcointalk.org? I know Satoshi started the original bitcoin.org forum, but I think the move to bitcointalk.org was a decision made between theymos and Sirius, with consensus among other old members. If I'm not mistaken, Satoshi was already gone at that time.
