I know the argument, and I even get it to a point, since I've had the odd, "oh, you're an American writer, aren't you?" moment when reading Pros. But it doesn't bother me enough to bother me when I meet it in stories, so long as the writer is engaging my attention and enjoyment.

I'm not giving up my weird spellings because they're a part of me and my identity on the net. Yes indeed, Blair has an ass, and a very nice one it is too, but I need to be able to have Jim wax lyrical about the colour with a u of his eyes.

I guess the short answer is that you can't please everyone, so you may as well please yourself. :-)
