In case you haven't noticed, I think it's a neat article, agree with it, and think you should read it, too.
Interestingly, the article points out several iterations of Sue I hadn't thought of, including "blameless survivor of vicious divorce Sue" and "balding and middle aged yet irresistibly sexy Sue." The latter I've always had some sympathy for - being male and therefore perhaps one day doomed to male pattern baldness - but the former has always annoyed me. I even saw it in an otherwise nifty Escape Pod story once.
Anyway, I will leave you with these thoughts and an article to read, for now.
