That's the way I use my weblog, greg.org, but for films. When I'm in production/development on something, it's mostly war stories from the set/editing room/festival fray.

When I'm...well, when I'm writing a script, and not ready/in the mood to disclose/discuss it explicitly, I post the raw inputs, from which one could "extrapolate" the movie.

Except that the product is completely different. When did Gibson say he'd probably have to stop posting on his weblog when he went into bookwriting mode?
