I think both would be useful.

If I do the book, I'll do it through some medium like Leanpub so I can put out drafts to many people and get feedback. And after 18 months or so, I'll put the posts up on a blog so people can comment forever. But the nice thing about a book is that it's done; I don't want to be forever updating the material.

The how-to website would be cool. There's a lot of info out there that isn't well captured.

If you're excited to jump in on a related effort, there's the Lean Startup Circle wiki: http://leanstartup.pbworks.com/w/page/15765221/FrontPage

Sean Murphy in particular has done a ton of great work on that.
