I am SHOCKED that QR Codes actually happened. I would have *never* bet on this ridiculous tech, but as soon as all phones built it into the camera app, then restaurants decided that a QR code pointing to a freaking PDF in Dropbox was a valid menu, it was over. The avalanche had begun, and it was too late for the pebbles to vote.
@shanselman I would have preferred a QR code pointing to a nice accessible HTML page. Too bad PDF was easier to retrofit into existing tools.
