As i was proofreading the final draft of my chapter of the O'Reilly book, i kept running across certain sentences and thinking to myself, "That doesn't look right. I don't think i would have written something like that." Finally i went back to compare it to my submitted draft. Sure enough, the editor has gone through the chapter and replaced all my attempts to use the singular gender-neutral "they" and "their" with masculine pronouns "he" and "his", etc. Even "he or she" was replaced everywhere by "he". Sigh.
I'll ask for a correction, but i don't have high hopes since we've already been through a couple of rounds and we're really on the final final draft.
