Ooh, you've piqued my interest now. Will be interested to see what turns up. I think most of those points could be a post in themselves (some of them many posts). But knowing you, you've come up with a creative tangent :)
I could say, wait and see ... :) The point re character interviews sparked with me - I've done two character interviews recently & another one soon to be published as a guest - so why not bring them together for a blog post (with links to the original interviews).
Sounds like a great idea. Back links are always good. Though if you bring too many interviews together, you'll have a screenplay. LOL - I should stop before I give you any more ideas :)
