I just wrote a blog post
on the fact that I rarely discuss stories that I'm working on, despite the fact that this means I don't get a feeling for whether my choices work or not until the first draft's done and someone's reading it.
Do other writers take this approach of disappearing into a hole until there's something complete to show? Or do you have people you can bounce ideas off at the start of the process or while the writing is in progress? How useful do you find this feedback and how does it shape the resulting draft?
(And I apologise that this is another writer-centric, rather than reader-centric discussion. I'll have to think of a topic more accessible to both next time)
