Internet privacy is like a living room window: people occasionally glance over if the curtains are open but most of us do not shut the curtains for fear of someone trampling across the yard and peering in.
We are more likely to shut the curtains when the living room is a mess, when we are naked, beating our step-children, or otherwise having a private moment, but most of us don’t barricade ourselves in our homes for fear of being seen from the street.
