Jeff VanderMeer shares his hard copy edits to a story. If you think your pages bleed from the amount of red ink on them, just look at that picture.
When Teresa Nielsen Hayden ran her party trick (ie. "watch her edit your story in real time") at VPXIII I asked her if so many comments were usual for a submission level manuscript. She said yes, but I always had a sneaking suspicion she was trying to make me feel better (or at least that's what the goblins gibber in my ear as I go to sleep).
So this helps. Thanks, Jeff, for sharing.
