Krugman's argument for a return to Keynesian economics

Okay this is how big of a nerd I am:
Despite being really tired from a long 6 am - 12 pm day, I came home and was incredibly excited to finally read this Paul Krugman article in the New York Times Magazine. Although it kept me up until 2 am (what?? I'm a slow reader), it is one of the better economics pieces I've read in awhile....and as a result, I slept very very contently. On top of that, it has both challenged and helped the way I view the policies that shape our economy.

Although Krugman is a slightly biased towards Keynesian economics vs neoclassic/Friedman economics, he raises some very interesting points throughout this article. The best part about it, though, is that his prose is very simple and easy to understand--especially for those of us who aren't economists. He briefly outlines the historical trends in economic thought since Adam Smith, and does so in a way that is not only interesting, but also in a way that also drives at his central thesis: that economists and policymakers have to steer themeslves back towards the ugly and unsimplified theories that existed prior to neoclassic/Friedman economics. I'm not going to even try to capture his thoughts (you all should read them for yourself), but they are really good!
