I'm not sure if the general population really knows what to do with these yet, but they are definitely becoming more prevalent. I do have some concerns with accessibility, however, because putting this square barcode on your business card is like saying "you have to own a smartphone with a camera to get to know me."
So great, now I know how to make one - but where should I have my QR code link point to? This blog? Well, out of context it might be a little abrupt (see penis model post). I needed to establish some context first, so I decided to create an about.me landing page that links to all of my virtual identities.

Once I linked my about.me page to LinkedIn, I realized my resume and profile photos were outdated. So, the simple project of making a QR code led to creating an about.me profile, which led to updating my resume.
What I learned: When it comes to QR codes, one thing literally leads to another.
