[The Internet] affects democracy... As more and more citizens express what they think, and defend it in writing, that will change the way people understand public issues. It is easy to be wrong and misguided in your head. It is harder when the product of your mind can be criticized by others. Of course, it is a rare human who admits that he has been persuaded that he is wrong. But it is even rarer for a human to ignore when he has been proven wrong. The writing of ideas, arguments, and criticism improves democracy.
