So I (I hope) politely responded that most of the mistakes were not in fact mistakes but variances between English and American English.
However, thinking about the difference in spelling between American and Non American English does raise the issue of where and when to use either.
Do I remain obdurately Australian and write only in Australian English? Or do I go all the way the other way and use just the American spelling? Or better yet, choose my language to my main target audience.
I like to think that I have chosen the latter step as, so far at least, most of my known reading audience, seem to be non-American and have no problem with my English. Of course if I were to write to a mainly American audience, then I would happily converse in the language that they are more familiar with.What about you now? Do you know what is the common denomination between you and your audience/market? And are you aiming for that or simply and maybe even arrogantly just going your own sweet way? Well I have had my say now, what say you? And in what language?
