Very nice. This combines two of my interests, book writing and tech startups. :)<p>First impressions: the homepage looks good, nice and neat, but doesn't communicate "what's in it for me" to the user easy/fast enough. You have a great video demo, but I didn't even notice it was there until after I read comments here. Just do a screen capture of the page with the video, crop the video image, and stick that on the home page as a link to the video. Pictures are so much more engaging for visitors than just text.<p>Next, the FAQ and video demo, etc. should exist on the same site design as the homepage. I can understand this is an early release, and the crowd here at HN is familiar with Posterous, but anyone from the outside would think "huh?" when jumping to a different looking page. It doesn't look as professional.<p>The actual product looks very cool, simple and effective, as it should be. I especially like the character name generator. :) I think the site should also be clear about how the author's work is safe. As a dabbling author I will certainly bookmark this site! A feature request would be to see an overview of everything created -- characters, scenes, etc. -- on the same page to provide a good mental outline of the book for the author.
