Joining this debate late. But worth bumping in case anyone didn't read it last week. Because it is outstanding stuff.
From a PR point of view I have always been taught, just like Dennis says, to concentrate on your positives; not slag off competitors; and, focus on your own business.
However times they are-a-changin.
If, in my experience, Duane is anything - he's as transparent as they come. Transparent on a stick. If he thinks it - he says it. Which is why is so compulsively interesting for journos.
In times when businesses are encouraged to be less covert and more open, it would be a shame if bad experiences with journalists caused Duane to button his lip.
I've been preaching to clients for years to think carefully what you say. And tell people what they want to hear not what you want to say. But to be honest, nowadays that stuff just gets lost in a bundle of media mediocrity - if it gets picked up at all.
People want passion, honesty and character. And they want to do business with people who display it in bunches. Twitter can help you show the world what you're made of.
