The blokes over at Stupid Business Ideas were trying to come up with just that — a new, stupid idea for a business — when they brainstormed the concept of AdAid. But when they actually looked up the domain, they found that it redirects to social network Facebook. Mark Zuckerberg has a soft spot for charities, if proto-application Causes is any indication. So perhaps the company is looking to Bob Geldof to sign up a roster of superstar celebrities who will sing songs and give heartfelt lectures in the hopes of guilt-tripping corporations into maintaining their ad budgets through a possible recession? I don't know, but I'm willing to bet $20 that Moby is composing an original song for the event already. (Illustration by Stupid Business Ideas)
