Very interesting article!
It makes me sad to know that today's writers and publishers don't pay as much attention to spelling as they should, though.
Even worse than a writer who can't spell, though: a writer who's overall sloppy. I mean, you can tell the difference between an honest misspelling and someone who just spews out words without caring at the slightest how they appear on the paper.
I want to say that even they can have great ideas and end up writing something great, but... I'm having trouble. I'm of the conviction that if you can't be organized enough to write a structured (even though misspelled) text, you can't organize your ideas either. I'd expect the piece to be full of plot holes, jumping from one scene to another etc..
You can shoot me now.
