I’m on the last day of my trip to San Diego, sitting in a Barnes & Noble using their wireless connection. Next to me is an otherwise-normal-appearing middle-aged man, in a suit, sitting in an easy chair and talking on his cellphone. One would think that he’d be talking about work, or maybe what to bring the kids home for dinner… but nope, he’s engrossed in a conversation about his Grand Theft Auto skills. Awesome.
