(abbreviated from Quick Response code)[, it] is a specific matrix barcode (or two-dimensional code) that is readable by dedicated QR readers, smartphones, and, to a less common extent, computers with webcams. The code consists of black modules arranged in a square pattern on a white background. The information encoded may be text, URL, or other data.
In the interest of experimentation, I generated a QR code for this august journal using Kaywa's free, online service.
If you have a smartphone, you can download and use a QR code reader app for free. Fire up the app and do a quick scan of your laptop/desktop screen to surf to one of the finest blogs in the 939 area code. And remember to bookmark it on your smartphone for a daily panoply of real news, opinion and shiftless frivolity.
Of course, if you're viewing this post on your smartphone, this could be one of the most useless blog posts ever.
