I don't know if any authors have already done this, but, as a reader, what would you think of an author offering their own commentary on their work in the story comments as the story posts as a serial? So, after each chapter, the author comes in and says, "Here were my goals for chapter x..."
Would you find this insightful? Would it piss you off? Would you interact with the commentary? Has anyone already done this? If not, is it worth a try? It's something I'm considering doing for "A Healing Love".
