some times wonder if it's worth building a service where someone pays a pittance as a test fee and then gets presented with whatever you can get together on them via RTB ads

because just showing someone the amount of data carried in an RTB packet is too disconnected from reality (which gets closer to "the bidder probably has your house geolocated just from the ad data on that one add the android app shoved in your face without warning"

(of course, the RTB houses would likely want to kill such a service because it would show just how much shit they tie together)
