One of the things I appreciate about the Internet is how it gives voice to people you'd never hear from otherwise.

For instance, New York Times columnist Nicholas Kristoff recently wrote a column lamenting the fact that Americans are losing faith in free markets and the financial industry, and how on a trip to a college campus he was surprised by a student who asked him if it was immoral to seek banking jobs. Kristoff's column was dumb, but I'm not going to go into all the reasons why, because the student he spoke to, Jon Emont, has already written a piece on Slate explaining why Kristoff is wrong.

Pre-Internet, Kristoff would have written his column, and that would have been that. We never would have heard a peep from Jon Emont, unless he wrote an angry letter than happened to get printed in the paper. But now, thanks to the Internet, the likes of Jon Emont have options, and places to tell their side of the story.
