QR Codes

Doing some experiments with QR codes and their use in publications.  Also the recognition of their use by the average consumer and their ability to use them.  I did a quick and unscientific survey at the local swim club lately and only two out of ten adults had ever used them.   Three out of ten could tell me what they were.   Here the local paper has just started to use them in support of stories.  At the right, a QR code for this blog you can scan with most smartphone based scanners.
