The Internet is a huge boon to free speech -over 2 billion webpages are out there, showing people's thoughts, dreams and stories. Whatever you go looking for, you will find. The Web is Caliban's mirror - when I go there I find a community of intelligent discourse, wry jokes, technological assistance and the greatest works of human history, lovingly transcribed by those who care about them. Oddly, when Jack Valenti looks there, all he finds are thieves, hucksters and crooks.
