QR codes are everywhere now. Not literally, but almost. Consider the following examples...

The big question is: are they here to stay?

What I mean is, are they popular because people are using them, or are they popular because marketing folks think people are using them (or WANT people to use them)?

For example, I see them in maybe 60 - 80% of ads I see now days, but I only see them in 10 - 20% of publication articles. Is it that the advertisers know something publishers don't? Or is that the advertisers want to create a reality that the publishers know isn't the case yet.

I suppose it kinda comes down to a chicken or egg discussion, but what I'm really after is - are they here to stay, or are the going to got he way of the slap bracelet?
