Let's go back to banner ads that are "targeted" based on what type of website you're looking at, rather than based on vacuuming up as much private info as possible about users.
It seems to me that as long as advertisers have ingenuity they will find new privacy harming ways of tracking us -- it seems like Goggle is moving earth to use their ingenuity instead to make a tracking device that isn't 'too identifying,' and could reasonably form the basis of a 'truce' between users and advertisers -- maybe we should let them?
