Thanks to polar ice melts, $100 per barrel oil prices, and an inevitable generational shift to people who have grown up hearing about environmental destruction arriving in positions to influence opinion, consumption and policy, sustainability seems to be emerging as the new buzzword.

My favorite post so far is Where the Brain Gives Pinky a Lesson in Statistics. Pinky and the Brain are a duo of cartoon mice who plot to take over the world. Correlation, causation and third-party logistics have never been so entertaining.
