Do You Speak American?

A review of "Do You Speak American" in the Philadelphia Inquirer piques my interest in the book even more. A peek:

Because of the disconnect between the written representation of spoken language and the way people actually talk, most Americans feel that the way they grew up talking is somehow inferior to the accepted standard. Some experts, such as Oxford English Dictionary editor Jesse Sheidlower, seek to record all these variations. Grammar prescriptivists, on the other hand, think the language is going to hell in a hand basket. MacNeil's conclusion? "People treasure their local accents, precisely because where they come from, or where they feel they belong, does still matter."
