I do wonder sometimes how all the data collected about me is actually being used. If anyone is buying it for targeted advertising or to observe trends for advertising purposes, they are wasting their money. I (and my entire family) aggressively avoid advertising. Everything is adblocked, and if it isn't adblocked I avoid it. I even try to avert my gaze from billboards and have bugged my state representatives to be more like Vermont and Maine and just ban the eyesores.
