From William Safire's "A Columnist's Farewell: How to Read a Column" (via Amardeep):
9. Cherchez la source. Ingest no column (or opinionated reporting labeled "analysis") without asking: Cui bono? And whenever you see the word "respected" in front of a name, narrow your eyes. You have never read "According to the disrespected (whomever)."
10. Resist swaydo-intellectual writing. Only the hifalutin trap themselves into "whomever" and only the tort bar uses the Latin for "who benefits?" Columnists who show off should surely shove off. (And avoid all asinine alliteration.)
11. Do not be suckered by the unexpected. Pundits sometimes slip a knuckleball into their series of curveballs: for variety's sake, they turn on comrades in ideological arms, inducing apostasy-admirers to gush "Ooh, that's so unpredictable." Such pushmi-pullyu advocacy is permissible for Clintonian liberals or libertarian conservatives but is too often the mark of the too-cute contrarian.
