I uploaded this QR code to my Flickr stream today. It points to a web address that’s not published anywhere (and absolutely nothing links to it) and contains a secret that should be pretty impossible to guess (try scanning the code to see what I mean). I have a small php script on that site to log visitors, the idea being that I can get some estimate of how many people actually recognize these QR codes at various locations.

I eagerly waited for the first hits. I waited some more. And then, 10 hours later, I got my first hit – from Googlebot!

So the question is, does google spy on my Internet traffic, or does googlebot read QR codes found on the web? Either way, it’s pretty interesting.
