In other words.  We speak english?  ;)

i'm Australian, we use the exact same spelling the British use

I got a good hoot from reading this thread. Nothing is more glamarous than seeing an English person say that Americans misspell "colour." How is spelling it "color" an error? That makes no sense.

Anyway, English is English. Calling the American use of language "lazy" is asinine. In the end, humans are built on efficiency. Think about most things and the entire essence is efficiency. Guitar? The essence of economy and economy picking. The human body? Does not waste energy and stores it for later use. Fuel efficient cars? Built a certain way to get the most fuel per kilometer. Academics? The introduction of multiple choice and scantrons or the use of teaching assistants to aid in marking. Business? The least amount of money you can spend while making the most. The list goes on. No one wants to jump through hoops of fire to accomplish a simple task.

::chuckle::  I think the OP is just fine.  Nothing wrong with wondering which style of English is used most or has the most influence.  But the whole my English is better than your English / your English is my English but screwed up / your English misspells words, that's all just dumb.

I have no idea, but I'd say American English, simply 'cos the US is far bigger than Britain. Also, like 99% of all English-spoken movies/tv shows, series etc. are American.

The Oxford Dictionary (as the oldest and most popular English dictionary in the world) will do just fine.

In that case, I'll spell "pneumonoultramicroscopicsilicovolcanoconiosis" as "cheese". It's a hell of a lot faster to type, isn't it?

I had to learn British English... 

And I have a feeling most English teachers prefer to teach British english (Foreign English teachers)..?

You got the idea Kantor.  Now if you are able to get many people to accept this concept and use it, then cheese will become an accepted way to refer to pneumonoultramicroscopicsilicovolcanoconiosis.

 i've been studying english for some years, (from dom rep btw), and what ive learnt is pretty much american english, and probably most of the english teached in latin america is the american english. i love the british english is so much easier to understand when watching movies.
