Steve Ballmer is an enthusiastic guy. As he climbed on stage with Danny Sullivan at SMX West, everyone was wondering how long it would be before he cranked up the volume and slipped into his typical Ballmeresque bombastic delivery. Steve didn’t disappoint. A few minutes into the interview, with Sullivan probing about Microsoft’s aspirations around search, Ballmer was yelling “Sell..Danny, Don’t Yell!” (ironic in the extreme) and roughhousing with poor Danny like a good natured football coach having a little fun with the class math geek. I half expected Steve to give Sullivan a noogie.
