Several people over the past couple of weeks have asked me what i thought about the Murdoch takeover of the Wall Street Journal. I don't have a whole lot to add that hasn't been laid out in stories and commentaries in the New York Times, Business Week, and the Wall Street Journal. Basically, I'm not concerned short-term. I don't think Murdoch spent $5 billion to ruin the reputation of the now crown jewel in his media empire. No, what worries me is when the septugenarian passes away. I don't see a management structure and dynamic sucession behind him. That's when I worry about the future of the nation's premier newspaper.
