Opinion goes in waves. People surf them without even thinking about it. Don't know what I'm talking about? It's simple. Major companies like Microsoft and Mozilla have already included in their browsers the ability for users to tell websites not to track them. Apple is doing that in their next browser.
What's the point?
Are you aware that mobile carriers know exactly where you are if you have your mobile device connected to the network?
Are you aware of the video vigilance cameras on the streets, malls, stadiums?
Do you care? Have you ever had any harmful consequences of that exposure?
Aren't there ways to keep your browsing history, cookies, etc, clean?
Let's not go paranoid about this!
