Re: American English v. British English - AE wins by 250 million votes
As it should be. It's the English language afterall, so why should it be taught the American way?
Personally I don't really care about most differences either way, although being an Australian, our language is all taken from British English rather than American.
But there are certain spellings where I prefer the American English, and some I prefer from British English. For example, I always end words with "ize" even though it's "ise" here. But seeing "judgment" just bugs me furiously, and the single "l" on words like "traveling" always looks off to me, although I occasionally write it that way.
Aside from that, I really couldn't care less either way about the other examples. Occasionally I use the American English versions just to remain consistent on American dominated sites, and other times I stick to British. Although for most of those I wouldn't know which is which, and just mix and match whatever feels right to me.
I'm not sure what you mean by "win", except in a humorous way (which I guess it's the point). Due to the difference in population between the two countries, I suppose there are more native speakers of American English than of British English, but BE is the most commonly taught internationally (Europe, Asia, and South America at least). Not to mention Canadian English, Australian English, and New Zealand English, which are closer to BE than to AE.
