These are experiments in QR Codes. At the moment they bring you to a dummy page that I'd like to make a reality eventually.
I think they can be an incredible new way to engage audiences. I see nothing but potential in this technology.
Imagine a world in which you can engage the companies you like on your own terms. A lot of people are afraid of privacy, but I think that this gets around that issue nicely. You actually invite more content by scanning the code. Thus, you only get the advertisement that you really want.
But speaking of privacy, wouldn't it be great to only be advertised things you might really want? I feel like the filter on my brain doesn't need to be as active if advertisers already know to not bother with pitching stuff to me I won't ever want or need. The question "what can they do with all that information they have about us?" always comes up when talking about the future of media, but I have to counter it with, "what would they want to do with it?" The only thing that makes sense is to sell us stuff. . . which is exactly what businesses have always been doing. Now they can more accurately target us. Targeting is a good thing. It keeps you from having to deal with Viagra and Lipitor commercials when you're 15 and from dealing with World of Warcraft ads when you're 72.
Anyway, aren't QR codes cool?
