AT&T is going to track and monetize the webpages you visit, the time you spend on each, the links or ads you see and follow, and the search terms you enter if you have their new gigabit broadband service (such as in Kansas City). If you don't want to be tracked, "fortunately" they let you opt-out for a $29 / month fee.
