Progessive/Productive Or Non-progressive/Nonproductive?

It must be exhausting, being an advocate for prescriptive DA...I imagine that those who live in a world of how discourse should be instead of how it actually is feel either like Don Quixote or the Cassandra of Greek mythology. I certainly don't have the stamina for it...besides, I think descriptive DA makes more sense. Given that Bakhtin sees discourse as ongoing and unfixed anyway, I'm sure he'd scoff at the concept of placing value judgments on discourse.

In that spirit, I'd like to pose a question: Is this discourse progressive/productive? Why/why not? If you feel it is non-progressive, how wide does your lens have to get before you see it as progressive, or does your lens never get to that point?

Inquiring minds want to know...
