I finally got the story behind Bono's alleged appearance at the Demo tradeshow last year. MindTouch cofounder Aaron Fulkerson recruited the singer from a U2 tribute band — Pavel Sfera from San Diego-area Desire — to walk around the show floor and do his shtick for laughs. Sfera, shown here with telejourno Natali Del Conte, turned out even better than the real thing: He ad-libbed monologues about Mother Teresa, Desmond Tutu and Jesus all over the place. Because of the real Bono's role at Elevation Partners, and oh just maybe an oversized sense of their own importance, Demo attendees believed what they wanted to believe: Saint Paul of Clontarf had come by their show to check out their startup! Fulkerson had to hustle Sfera out of the show after founders began excitedly pitching him. "I've got a cure for hunger," one gushed. It involved Web page markup technology.
