In Writerdom it's generally considered bad form (downmarket, gauche) to tout one's letter to the editor. Not much of a coup, as things go; no money changes hands. That is far less true, however, when the letter appears in Harper's, where the cut is brutal and the opinion-leading reach extreme. Thus I commend you to my letter in the February issue, which Harper's editors have smartly titled "Why Trump Towers." (Scroll down to find it.) If you're a Harper's print subscriber, it's on magazine page 98.
