Thank you to those helpful on the sticky questiong of (US/World) Grammar, especially woodsman's game.

Style books are employed as needed though it must be said that, unlike the style reference mentioned by w.g., the style books used are mainly media oriented. It should also be said that past "screwy" education on my part can now be seen as both archaic and international in scope, making the use of contemporary grammar that much more dicier.

So, as others have alluded Grammar should just take a second seat, priority-wise, and one should forge one a s best as possible. This technique seems like stumbling around in the dark, but at least does not usually present the worst of evils.
