Marketers have been slapping QR codes on just about anything and everything to tap into the mobile media market.

As consumers, we initially bought into this gimmick, snapped a photo with our smartphone and then got disappointed with the content we received. Just when we’re about to give up on the content delivery system (hey, we’re lazy), we get this cool pint glass that is one giant QR code. However, the code isn’t scannable or readable with just any beer, it only works when Guinness is poured to the brim.

Pretty clever. But what’s the payoff? According to AdWeek, it “tweets about your pint, updates your Facebook status, checks you in via Foursquare, downloads coupons and promotions, invites your friends to join you, and even launches exclusive Guinness content.”

Of all the beer brands, Guinness has the most diehard fans, so this should be a win, but as cynical jerks whenever we see ‘exclusive [insert brand name] content’, we know it’s gonna be a crappy wallpaper. Fortunately, even Guinness’ crappy wallpapers are pretty boss.
