Posting your story here as you write it will get you instant feedback so you can see what works/people like, and then if you hit a roadblock then they can offer suggestions and support for how to overcome it.
I should have done that, but I am getting close to done. I really like what I have so far. At this point I would like to get it to where I feel it is ready for someone else to read. I might ask a few people to read it before I post it.
I think when you are writing you know what you mean to say, but if someone reads it and says hey who is this guy?, or why did she do this? etc. that you realize you forgot to include some things, or didn't explain a decision enough.
I plan to release it as a .PDF to preserve the formatting the way I have it.
