user2572: I am looking for informations about the authors of the current symbol used for Bitcoin. I am also interested about any brand design explainations such as graphic guidelines, and the way this symbol was adopted (contest, vote, imposition…). As a supporter of the symbol Ƀ, I am not sure this choice was right.

He never posted much about why he chose this symbol. It was not in use before Satoshi put it in the logo.
The current Bitcoin-Qt logo was created by bitboy:

This logo replaced Satoshi's old one when the bitcoin.org GUI was rewritten from wxwidgets to Qt by Wladimir van der Laan. I don't think there was much discussion about it.
