Great visions! I absolutely agree with emc2. The scientific attitude should be pushed as much as possible and is in my opinion the most important if not the only point of this coin *thumbs up

edit: the "emc2 accepted here" signs can not be bad for the currency though. Even if nobody pays with it, it's good marketing to have a shop offering it as payment method. Makes it look trustworthy

edit2: I will start working on poster layout for universities on the weekend and try to put in the above ideas. Universities are the perfect place: a social reach of several thousands per poster and even the professors/researchers will get an idea of it.
