How is "y'all" doin'?

Wait, that’s not what I mean…

I grew up in “y’all” country. “Y’all” functioned beautifully as a second person plural pronoun. Now I live in “you guys” country. That seems more awkward. It can push the boundary of informality a bit much, and may offend some gender sensibilities. Using just plain “you” and trying to telegraph your plural intent is also clumsy.

If there is anything like a natural selection in the evolution of language, then it seems like “y’all” ought to thrive. It just beams with linguistic fitness. So my question is, is it in fact thriving? Is it still used as often in southerly climes? Is its range expanding or contracting? Or is it destined to be a collateral casualty of the general attrition of regionalisms?
