Sorry, I don't speak English.

So, I logged into Facebook this evening and received the following notice:

Hello Nick, do you speak English (UK)?

Help translate Facebook into English (UK) so that it can be used by people all over the world, in all languages.

Hmm, so if the site is not already in English (UK) then what language is it in, and when did I learn it?

Seriously though, this is a great example of how us English folk find ourselves speaking a 'regional' dialect of the language, rather than just plain old English.
