I agree with your thoughts about roll call. I know privacy can seem over rated but its also an important aspect of being truly free. In an information age so much is about having the right information at the right time. If we don't do anything bad, we have nothing to be afraid of right? Not necessarily, with your personal information in their hands large corporations will implement better approaches towards influencing you to buy their products and use their services, ways that may be subliminal in many regards. Privacy is underrated until we have none left at all. Thanks for your thoughts.
