Actually, this is a very interesting site.

You will find certain words or phrases criticized here listed in dictionaries. Note carefully labels like dial. (dialectical), nonstandard, and obsolete before assuming that the dictionary is endorsing them. The primary job of a dictionary is to track how people actually use language. Dictionaries differ among themselves on how much guidance to usage they provide; but the goal of a usage guide like this is substantially different: to protect you against patterns which are regarded by substantial numbers of well-educated people as nonstandard.
