I ponder this because in my writing classes, I teach them that writing is an iterative process, and that the more eyes on your work the better, and that they want to hear as many responses to their work as possible. I do think that’s true. But then it struck me that your choice of when to invite people to offer feedback is highly individual and may speak a good deal to people’s writing style. I sometimes wonder whether people’s writing issues can sometimes be linked to when they choose to share.
