''ve been to the United Kingdom on a few occasions, and I have noticed that there are no Zs anywhere. The word 'realize' is seen as 'realise' for example. What's up? I can't see that you could stop using the letter Z altogether (how could you say 'zoo' or 'zebra'?). Is it just select words that you have chosen to use S as opposed to Z? Or is it just select words that Americans have chosen to use Z as opposed to S? Somehow or another this will degenerate into Europe vs. America mud-slinging...
