Do Not Track turned on by default
In one of the gutsiest moves Microsoft has ever made with Internet Explorer, IE 10 ships with the Do Not Track header turned on by default. Although the header relies on website cooperation to put a dent in different kinds of tracking -- and the details of DNT are by no means set in concrete -- there’s no question that Microsoft’s come out on the side of the consumer. Of course, after Microsoft made its DNT announcement, the draft proposal of the standard was updated to require users to opt-in to the policy in order for it to take effect, thus rendering IE 10 non-compliant. No doubt DNT remains a moving target that we'll be hearing about more in the years to come.
