First of all let me make one point clear here as it's something that is often quoted but is usually incorrect. The American spellings of such words as 'color' 'favor' etc. are not necessarily wrong. Only a few hundred years ago there weren't any standard English spellings. If you've ever read any old books in English you'll quickly realise that the writers more or less made things up as they went along.
English people emigrated to the New World and they took these spellings with them. So American English is not wrong and the people using it are not lazy (as I have seen some people claim) they are merely using the English that they took with them to America. One could argue that in some cases their English is more like traditional English than modern British English is.
So let's not decend into slagging off Americans here.
Now then - I'm a great believer in protecting that endangered species, the humble apostrophe. I hate to see it used incorrectly and cringe when I see used in the wrong context.
