This kind of “sharing” — this hyperpersonal opening up of the most intimate and safest aspect of one’s life to a stranger — is not present when you hire a person to fix a leak on TaskRabbit, or when you get into someone’s air-conditioned black car for a silent ride to the airport with your head in your phone. More than anything else, it is this aspect of Airbnb that distinguishes it from Uber, Lyft, and any other of its sharing-economy peers.
