This is always relevant! I can't count the number of times I have shown this url to people discussing QR codes. And I am still waiting for the shiny day I find some creature "in the wild" conducting a QR code scan.

The "process flow" of someone scanning a QR code is longer than taking a photo, and the expectation is to reach a website.

I find QR codes useful for getting private keys for my server onto my phone, Google two-factor uses them for the same reason. I might be an edge case, but yeah.. :)
