@Ferndok JohnOfStony was trying to reduce the spread of this error. The person that pointed to Wikipedia has made a mistake precisely because of the widespread use. You'll notice that the Wikipedia article said common use or to that effect. A dictionary often specifies common use and CORRECT meaning. It's sort of like the word centre is spelled center in America. someone got it wrong and the error perpetuated.
A minor criticism - WDNW is NOT an acronym; it's an abbreviation. An acronym is a word whose letters are the first letters of a descriptive phrase, e.g. laser (Light Amplification by Stimulated Emission of Radiation) is an acronym. BBC (British Broadcasting Corporation) is an abbreviation because it doesn't spell a word. Incidentally, this error is now widespread in the media. I'm just trying to stop it spreading.
