QR Codes

I don't see the point in QR codes to be honest. It's like the people who put them up assume that everybody can read them while in reality only a very small minority of people can actually make use of them. I believe that a bar code works just as well.
However I still made a list of 5 QR codes:
Wikipedia

Google

Yahoo

Flickr

Steam

I like most of these websites however I don't use Flickr but on the rarest of occasions. Was fairly easy to do but still disagree with it's usefullness.
