LOL, gold! I would buy that one too. As for the actual posters for sale, if people actually do want these on their walls, just type it in notepad and hit print. I'd sooner opt for a cheesy new age motivational slogan than Zuck-wisdom, but then I'm not a Facebook loyal.
These are too small (11x17? why wouldn't I just print them at the office?) I just ordered larger versions on vistaprint.
Zuck has never struck me as a particularly motivating individual, but I only know his tv personality side..
