The Tracking Protection Working Group under the World Wide Web Consortium is trying to work on specs for a Do-Not=Track browser feature. Jonathan Mayer, a Stanford grad student, is a big force in the group's privacy constituent -- and he's pretty pessimistic that the group will reach any real consensus on how Do-Not-Track will work. He tells AdExchanger that by setting those default settings to Do Not Track, "We give interested parties the incentive to educate consumers about the impacts of those choices. We allocate to them [those parties] the responsibility of getting consumers to give them access."
