I heard that all the cool kids with their cool sites had QR codes; those odd square barcode-y things that allow people with their smart phones to get more information quickly, hence the name. The quick response I've gotten so far is a pitying smile.
Of course, what I wanted was a comment on this blog. I told a customer yesterday that blogging without comments was like standing in my backyard talking to myself. She seemed to think that was a pretty good idea because if I was in my backyard, talking to myself, I wouldn't be in her driveway talking to her when all she wanted was her mail.
