Decent article on the questioning of dialects. Although common knowledge to many linguists, it's still nice to have different perspectives on this issue of "where" dialects originate. I think it's more of an interest to ask this same question in Eastern Europe, primarily in Romania (my current proposal is for a project to attempt to discover some answers to this question). At any rate, I thought I'd save this article for a possible future use.
