I have two daughters: One an open book, one a locked box. So the question of privacy is a challenging one. How much do kids need? How much should we give? How do we prepare them to live in a world where the very notion of privacy opens a generational chasm?

Our children will outwit us if they want; for when it comes to technology, they hold the higher ground. Unlike other tools passed carefully and ceremonially from one generation to the next - the sharp scissors, the car keys - this is one they understand better than we do.

Anyone with the right mix of parental paranoia and entrepreneurial moxie can make a fortune by selling parents the equipment we think will keep us one step ahead of our kids.
