I am sorry to see the down votes happen, but I can tell you that seeing your questions bring up memories of conversations I've had with friends and family about this issue. They, too, were curious about the issues of tracking and cookies, but in my experience nobody's opinion changes beyond their initial gut reaction, and extended discussion on the topic do not result in much listening-- only non-stop talking. So I wonder if the down votes in this thread are a silent attempt to discourage discussion along this route to prevent a flame.
