Please, no!

I love the variation that allows a sense of place in a "common" language. I can just know where the character in a novel is from by their idioms: Is it "couldn't care less" or "could care less", "pavement" or "sidewalk", color or colour etc? It only fails when the author gets it wrong. It's disappointing that regional accents have homogenised somewhat from entirely national TV programming in a country that must have 50 regional terms for a bread roll.

So long as we can understand each other, I delight hearing the more musical cadence of English from some non-native speakers, or the idioms of my Indian, Geordie, Scouse or Scots friends (OK, I confess it took me a little while to tune-in to full on "Weegie").
