I get that adding a QR code adds a tracking/metrics component to an organizations resources but as a user it pisses me off. Just put a human-readable URL there so I know what to do. I can remember www.poblanopete.com easier than I scan and load a page on my phone.
My town has a poster downtown that says "Scan here to see a map of this downtown area". WTF? Why not just put a fucking map there with an arrow that says "You are here?". It at least makes me laugh every time I see it.
We can have both and that's all I want.
