Working in the education sector it’s not the QR code itself that drives me up the wall, it’s the idiotic hype and spin around them.
Blog post upon blog post of “100 things you can do with a QR Code!” – which are all, basically, linking to a webpage where the actual content is. So those people should really write posts around “100 things you can put on a webpage” 😉
So it’s the ‘educational practitioner’ trying so hard to sound cutting edge spouting off about them that gets on my nerves. “Yes dear… it’s a URL shortener. Very good. Well done” 😉
