A new app called Surkus allows restaurants to manufacture their ideal crowd and pay people to stand in place like extras on a movie set. The app reportedly uses "an algorithmic casting agent of sorts" to hand-pick people according to age, location, style and Facebook "likes." All of this is done to create the illusion that a restaurant is busy and worthy of your hard-earned money. Chicago Tribune reports: They may look excited, but that could also be part of the production. Acting disengaged while they idle in line could tarnish their "reputation score," an identifier that influences whether they'll be "cast" again. Nobody is forcing the participants to stay, of course, but if they leave, they won't be paid -- their movements are being tracked with geolocation. Welcome to the new world of "crowdcasting." Surkus raises new questions about the future of advertising and promotion. At a time when it has become commonplace for individuals to broadcast polished versions of their lives on social media, does Surkus give businesses a formidable tool to do the same, renting beautiful people and blending them with advertising in a way that makes reality nearly indiscernible? Or have marketers found a new tool that offers them a far more efficient way to link brands with potential customers, allowing individuals to turn themselves into living extensions of the share economy using a structured, mutually beneficial transaction? The answer depends on whom you ask.
