Once a week or so I leave my house in the morning at the usual time, bag packed, computer stowed—but instead of heading straight to my office I go elsewhere. Specifically, I head to a very public, chain bookstore café — one with free wifi — where I order a cup of coffee, plug in my laptop, and work for a few hours before heading in to my office. The place is hardly welcoming. It’s the opposite of “Cheers,” where “everybody knows your name” — in fact, that’s part of its appeal. I am anonymous here, and I relish the anonymity.
