Just interested in this. What English dialect do you use for writing and I guess every day life? Yes, there is some difference between British English and American English (a long article): http://en.wikipedia.org/wiki/American_and_British_English_differences Even though the English language is not my native language, I have learned British English. I am well aware of Australian English and there is an Australian English option in OS X (click Apple-Shift-: in Safari or TextEdit). So far, I do not see any difference between Australian English and British English. So, what English dialect do you use? There's many: http://en.wikipedia.org/wiki/English_dialects It's just that British and American are the most common ones.
