That might be the day it was released to the public, but I wonder when it was conceived and how long it actually took him to develop bitcoin from his initial idea. It seems to me like it would have taken quite some time to figure out.
Well, bitcoin.org was registered in August of 2008 so it's safe to say Bitcoin has already been conceived, at least in SN mind. There are interesting bits and pieces out there but very little from the founder himself - he was strictly business and shared very little of his life struggle and personal journey thing with the public.
