Sorry it does matter. English is a wonderful language, in part due to its complexities and oddities. I don't want it to become Leftpondian or txt speak. Let's celebrate its diversity and quirks.
[fx: clears throat]
Having spent a considerable amount of time west of the Atlantic Ocean - where I believe lies this 'Leftpondia' of which you speak - I feel qualified to comment upon your remarks.
Rubbish!
Upon arriving in these
blighted blessed Isles I was shocked and disgusted by the 'quality' of English. From people on the pavements to signs in shops to internationally-respected newspapers, the English language is butchered. I knew enough about the differences between the varieties of 'North American' English and 'British' English before arriving here. These don't qualify as butchery (though some may disagree). I mean spelling, punctuation and grammar.
I would not be so foolish as to say that 'US' English is a better variant than 'UK', but in my experience the US locals seem to have a better grasp of their language. Don't quote the current US president or soundbites and 'vox pop' interviews - that can cut both ways.
I quite enjoy winding up the locals when I'm criticised for using 'American' words like Fall instead of Autumn. Do I need to point out which word is 'English' and which is 'foreign'?
There are times I would like to see more standardisation among the various varieties of English, but on the other hand I am not a supporter of American hegemony.
Live and let live, I say.
Viva la difference!
