I used to hold the Economist in similar high regard in the early 2000's. In 2004 they hired a new editor-in-chief and the quality of their articles began to suffer immediately. Their perceived thoughtfulness (as a function of independence and novelty, at least in my mind) took an abrupt turn for the worse right after the resignation of a single man. I can't remember the name of the editor, but I can remember lamenting his resignation to my friends.
