I am Mary Norris, longtime copy editor for the New Yorker Magazine and author of "Between You & Me." Forgive the typos, it's my day off. AMA!
I clawed my way up from an entry position at The New Yorker to page o.k.'er.
I started in 1978 in the archive and have worked in many different departments, and under four editors-in-chief. So I've seen the evolution of publishing firsthand, from typewriter to desktop publishing.
And over the years, I've copy edited everyone from John McPhee to to Philip Roth to George Saunders.
My book started with a blog post about commas on NewYorker.com. And punctuation proved to be a HOT TOPIC.
Wrote about other things, and turned it into a book, "Between You & Me," which you can learn more about here.

I'm here at reddit NYC with Victoria drinking coffee to answer your questions.
Update: Thank you all for your wonderful questions. I have to go now to MSNBC, where I'll be "The Cycle" at 3:40 PM EST. But I'll come back and take another look when I have a chance. In the meantime, I am doing a book tour (you can see details on http://www.commaqueen.net), you can follow me on twitter @MaryNorrisTNY, and I hope you enjoy the book.
