What is en_US ?

[Tim Alberts]

Here's a thought, how about quit making up new languages and start 
combining others.  It's a global society and it'd sure be nice if we all 
spoke the same language.  Being American I vote for English (because I 
don't want to learn something new), but honestly, I don't care if it's 
Spanish, French, Chinese, Russion, Arabic, pig latin, or something 
completely new (that is efficient and makes sense).
