Johnny Swifter's "Gadflyism 101" podcast deals with the use and misuse -- mostly the latter -- of language in public affairs and the problematic consequences that often result. He has a particular penchant for looking at publicly offered sentences and arguments that, though at first seeming sensible, perhaps even wise, upon further examination often prove meaningless or downright wrongheaded. Mr. Swifter has no qualms about criticizing the famous or powerful.
