Deep inside Facebook’s massive new headquarters, the largest open-office workspace in the world, a rough-hewn building that feels like the idea economy’s take on the industrial factory floor, sits the desk of Lindsay Russell. The desk is a white slab, 5-feet long, no drawers. The top has room for her laptop, computer monitor and a few knickknacks. Russell, a brand strategist, also has an office chair and small file cabinet. That’s it. No coat rack. No office phone. Her just-delivered dry cleaning, handled by Facebook, hangs by its metal hangers from the desk’s lip. There are no cubicle walls. No partitions. Her desk sits cheek to jowl in a pod with five other desks, a scene repeated across the cavernous Frank Gehry-designed space filled with 2,800 Facebook employees.
