The excellent Wall Street Journal online privacy series got me thinking of a new Venn of human-to-application interaction, sort of an evil twin of this one.
Intersection A ∩ C ∩ U might be a video that starts playing the moment you visit a site with sound you can’t turn off … showing you a marketing message that seems eerily connected to your ongoing search for a new car … when you realize the video is of yourself at home looking at car reviews online.
(Cue dramatic music.)
Unfortunately sometimes bliss is ignorance.
The really dangerous cases are when you don’t even perceive creepiness, irritation or lack of ethics… but your personal data is being abused nonetheless.
Agreed that the area in U that’s not shared by A and C is pernicious. Maybe B could have a better name so as not to imply that it has a non-empty intersection with U…
