If I use phrases such as "do this every time" and "obey the style overlord," take a moment away from this blog. Have a beer. Then come back and see if the phrase is still there.
If not, it was all a horrible, prescriptivist dream. If so, assume I had a beer too many.
Look, English changes every day. Add to that the bizarre aspects of newspaper style and the personal peculiarities of those involved, and you have a recipe for arbitrary rule-making. And beer drinking.
Did I mention? Beer.
