"Some thoughts on writing well"

From the Nota Bene section of the indispensable Arts & Letters Daily today is a useful article which encourages plain English by offering "some thoughts on writing well."

At my local recycling center, the first bin is labeled “commingled containers.” Whoever dreamed up this term could have taken the easy way out and just written “cans and bottles.” But no, the author opted for words out of the bureaucrat’s style book, and chose the raised-pinky elegance of a phrase distant from normal English. He also added poor spelling (“comingled,” also a correct spelling, would have been clearer) and pointless redundancy (the concept of “co” is already embedded in the word “mingled”). How did they pack so many errors into two words of modern environmental prose?
