Rupert Murdoch's Mind, 140 at a time

NYT's David Carr, on the News Corporation CEO's foray into Twitter: "The rules of effective tweeting for business leaders are no different from the ones for us mere mortals who want to both express ourselves and remain employed: Don't be boring, don't curse, and for heaven's sake, don't always be shouting about how some junior executive is really knocking it dead. Being interesting is the key to going viral, and on that score, I'd give Mr. Murdoch decent marks."
