Brad Frost and Craig Villamor, friends living in New York, both work in the world of mobile media and have a natural propensity for noticing QR codes around the city.
"It's become impossible to escape them," Frost, a mobile web strategist and front-end designer at digital ad agency R/GA, told Business Insider. "I started amassing pictures on my phone of the more egregious specimens: underground, hidden, impossible to reach, ambiguous or just downright wrong."
So he and Villamor, the principal design architect of mobile and emerging tech at Salesforce.com (you know, the company that just bought Buddy Media for about $700 million), started a Tumblr to chronicle the worst of the worst, appropriately called "WTF QR Code?" The blog encourages people to send in strange uses of QR codes that they spot around town. The pictures range from the weird (cookies) to the weirder (women's butts).
