I read this technorati article today Confessions of a QR Code Virgin
OMG are they really paying WordsOnTheFly to write stuff like this? my comments will probably get deleted so i've posted them below.
Mindfull of your instructions to commenting "Personal attacks are NOT allowed" all i can say is "ugh" is this really the best you can do.....?
What personal information are you worried about giving up?
Even the most cursory research would tell you that the only information available to the QR code provider is similar to that from your desktop browser eg "ip address"/handset type/browser type etc.
Unless you are sill enough to enter your social security number of your mobile phone number into a form (after reading the article...highly possible), my point is i think you should turn off your computer and unplug it from the wall just to be safe i'm not stealing your identity just by posting this comment.
To anyone who took the time to read this authors article I apologise on his behalf. If you invest 60 seconds reading www.Cognation.net/QR you'll probably learn more than reading this article.
As for the writer..."Personal attacks are NOT allowed" ....I tried.
