In your link: "The term is now somewhat archaic."

No shit, archaic. If you go back far enough, Wisconsin was known as the Far West, way out in the Northwest Territories. I've never heard one single person in Oklahoma refer to the state as being South Central. Some say it's Southwest and like to associate with the likes of Texas, New Mexico and Arizona, cowboy hats and snakeskin boots and all that rigamarole. A few think of it as an extension of the Great Plains states, or the Midwest, as those there think of it. In my experience, most people in Kansas think of themselves as from the Midwest. If you look at a map of the U.S., Nebraska and Kansas are definitely middle and the archaic "Midwest" states are anything but middle or west.
