To get an idea of how complete a picture they get, now multiply that by all the times per day you visit, the places you are when you visit, and how you connect. Maybe you read your Facebook feed in the morning with your coffee between 0630 and 0700, and you visit a few links that go to CNN or Daily Mail or Politico. You connected via your wifi at home, so now there’s a series of data points showing that you are home at that hour every day, and that you probably leave for work between 0700 and 0730. Maybe you go to those sites on your lunch or break or while waiting on the train, carpool, or even in traffic. That’s another time/date stamp with location. None of this is even counting the part where it tracks what you click, what you like, buy, talk about, think about, and how all of that dovetails with other information about your browsing habits, interests, and what kinds of things you’re searching for on the internet.
