England is the only English speaking country in Europe, and IMO British English is the correct English. I don't mind so much when Americans spell it color and armor, but some baltant mistakes make me want to claw my eyes out. In my experience when talking with Americans, they will frequently make the mistake of spelling it "dieing" instead of "dying" "lieing" instead of "lying", "to" instead of "too" mixing up "you're" and "your" etc.
I'm pretty sure that with some effort and the occasional spellchecker anyone who has English as his/her mother tongue can use it correctly. What bothers me is the lack of effort really. I don't need a dicionary to write properly in Bulgarian, and most of the times I don't need one to write in English. Why can't the US population make a similar effort in grasping the concepts of their own language is beyond me.
Note this is not an American bashing post, It's a reflection of my experience while talking with them over the Internet and in person for quite a while now.
