Quoting a former Google engineer when chatting at a conference... "If you've written a check, paid by CC, placed any online order, or otherwise surfed the net for online shopping since the mid 90's.... you are in the system. If you think you are not being profiled, you are being fooled either by someone marketing a product, or by yourself." This so-called "erasing" of your habits, routine, history, fill in the blank panic trigger word... you simply are not understanding how profiles on people are built. The political world and the online marketing world have mastered this over the years.
