[Prudence]

Isn't that an overlapping issue of marketing to the perceived community? If I was marketing a product in Appalachia, and I wanted to project a feeling that my business/product was part of the community (not from "outside"), I'd make sure my adverts included people speaking in the regional dialect.

Conversely, if I was a business owner in Appalachia, marketing to the rest of the country, I'd want my customer service reps to sound mainstream.

(And, were I an Appalachian parent, I might expect my schools to include as part of their history and literature programs selections from Appalachain history and literature, including works that reflected the dialect associated with the region, as a way of imparting the cultural history and values.

Incidentally, I would probably have gotten much more out of a class in Ebonics than I did from the Washington State History class that was required for graduation. Seriously. If you moved here your senior year, you had to take it to graduate. (we all took it in 7th grade.) Do I remember anything from that class? ANYTHING? Not one factoid. Given the increased mobility of our society, does it even make sense to require a state history class? And yet, no one bats an eye over that wasted chunk of time.)
