I came across John Mauldin, http://www.johnmauldin.com, when someone left a printout of his blog in a railway carriage. His "Outside the Box" column is free to all.
I enjoy his column, and I think some of you may enjoy it too. I especially admire his thirst for knowledge and his tolerance of diverse viewpoints. He actively seeks disconfirming evidence and the views of those who disagree with him. Imo, this stance is a model for what politics should be, and isn't :-)
