That excites me.
His book, in fact, I like because of the collaboration aspect. I once had a story going with some friends via a freeopendiary. Unfortunately, when we all had things come up at once and couldn't write, it ended up 'archived' (ie-deleted). Since, we've lost contact with a couple of the writers, and most of us only saved scenes involving our own characters. It would be awesome to publish it if we finished it, and this proves that it would work (it's sort of a dark story as well), but I doubt we could pull it off quite the same way given people are missing.
At some point, I might use what I have on my own. (Basically, one person started this and then people applied with unique characters and an opening scene), but I'd have to change thngs about it that belong to the original creator, or that involved other people. And my character kind of grew into being meant for this story, so it kind of makes me sad.
But I'm babbling.
