This is your big fat brain. This is your big fat brain on viral advertising, for which there is no cure. The headline “You Suck at Photoshop Returns” was enough to drag me in to a web of infectious viral advertising. So, if you are one of the three people (of which I was one) on the planet who has not seen “You Suck at Photoshop,” go straight to My Damn Channel and check out (I mean really spend some time with) the travails of Donnie Hoyle, the mythical master of fauxtoshop instructionals. Donnie is the invention of the folks (Matt Bledsoe and Troy Hitch) at Big Fat Brain, a viral advertising and interactive firm, which seeks to control hearts and minds (and pocketbooks) by introducing “advanced interactive elements” into the body politic. “You Suck at Photoshop,” though not sponsored by Adobe, has certainly raised awareness of the complexities of this integral twenty-first-century answer to penicillin.
