I know of one person so far who has preserved their blog into a book format. Did you know there is a company out there who can do that for you??
Bloggled.com will soon be offering a "Blog to Book" feature to allow you to bind all your entries together in a book format. You can even add pictures along with your entries.
Sign up for their free service to backup your blog and they'll let you know when this awesome service will be available.
