*I* object to pink/girlish covers. It affects the likelihood I'll pick up a book to see what it's about, and if I do read one, I'm more likely to avoid reading it in public, because I'm embarrassed to be seen with it.

So I object to publishers assuming pink sells more books, and I object to their stereotypes for what women will buy. Obviously the money is supporting their argument...

Then again, how often do publishers release a book with two covers and track the difference in sales, and whether or not those sales were to men or to women? Do you happen to know?
