My input (mentioned in several of the previous 1000 threads on this exact same topic, thanks for searching... ) is that people will figure out their own names for things.
No one calls the US Dollar a "buck" or a "greenback" because Congress sat down in committee and figured out some cool slang words for us to adopt.
Lay Chris some slack, not all new members understand the functions of a forum.
Anyway, I half-agree with you: The Satoshi isn't anything official. However, your example with the US dollar is irrelevant because "bucks" and "greenbacks" really are no different from dollars.
