QR codes and great expectations

Whenever I have a new idea I get carried away thinking how marvelous I am - don't we all. Recently I've had some fantastic ideas about how to use QR codes for information literacy - yet to be revealed. However, I decided that I may be getting way ahead of myself with expecting people will a) know what QR codes are and b) know how to use them. So I've created this quiz with the hope of some responses. If most answer 'tell me more' - I will. Also, I'm trying out this poll software so let me know what you think of it.
