Good advice, for bloggers and for everyone, from Wizbang:
Never say anything you would not be willing to repeat under oath.
Never say or write anything you would not want to see plastered across the front page of the newspaper.
Never write when you can speak.
Never speak when you can nod.
Never nod when you can wink
Well, I am not a winker but I would add, as lawyers always advise, "Say it in flowers, say it in mink, but never, ever, say it in ink." I'm afraid that I break all of these rules, daily, as I have a perverse tendency to actively resist PC just for the fun of it. Fortunately, I have no employer to object. That's the Maggie's Ideal Way of Life.
