Not long ago, I moved apartments, and beneath the weight of work and lethargy a number of small, nagging tasks remained undone. Some art work had to be hung from wall moldings, using wire. In the bedroom, a round mirror needed mounting beside the door. Just about anything that called for careful measuring or stud-hammering I had failed to get around to—which was why my office walls were bare, no pots yet dangled from the dangly-pot thing in the kitchen, and my bedside shelf was still a doorstop. There are surely reasons that some of us resist being wholly settled, but when the ballast of incompletion grew too much for me I logged on to TaskRabbit to finish what I had failed to start.

On its Web site, I described the tasks I needed done, and clicked ahead. A list of fourteen TaskRabbits appeared, each with a description of skills and a photograph. Many of them wore ties. I examined one called Seth F., who had done almost a thousand tasks. He wore no tie, but he had a ninety-nine-per-cent approval rating. “I’m a smart guy with tools. What more can you want?” he’d written in his profile. He was listed as an Elite Tasker, and charged fifty-five dollars an hour. I booked him for a Wednesday afternoon.
