One of my political fantasies (of which I seem to have as many as sexual fantasies) is that the English speaking world agree on common spelling and rules. I'd gladly accept some Americanisms for the sake of a unified language. These variants we have in English spelling give no benefits.

And while I'm on a rant, another thing I'd love to see abandoned is MM/DD/YY date format, which to my knowledge is only used in the USA. What an anomaly!
