"The point of being aware of the attentional commons is not to make it happen but to refrain from damaging it; to be aware of the valuable absence that creates space for private reverie, and indeed for the possibility of those episodes of joint attention that arise spontaneously and make cities feel full of promise for real human contact.

"What this boils down to: Please don't install speakers in every single corner of a shopping mall, even its outdoor spaces. Please don't fill up every moment between innings in a lazy college baseball game with thundering excitement. Please give me a way to turn off the monitor in the backseat of a taxi. Please let there be one corner of the bar where the flickering delivery system for Bud Lite commercials is deemed unnecessary, because I am already at the bar. The attentional commons is an idea that I hope will catch on among those who are in a position to make such sanctuaries happen: building managers, commercial real estate developers, and interior designers.

Once every twenty minutes, somebody in the room would have to deliberately hit a button to restart it, and thereby actively affirm 'Yes! We want some emo in here!' "
