I'm just surprised that it hasn't taken off in the West. It's super useful for a lot of things. I suspect that a lack of QR code implementation in apps for Facebook and Twitter has a lot to do with it. Kinda prevents mass adoptions when they haven't found a usecase for it, though all those Asian sites clearly have.
