WPBook enables users to add your (self-hosted, not wordpress.com) wordpress blog as a Facebook application. Facebook users will see your posts in a Facebook look and feel, and can leave comments with their Facebook identity.
Comments are shared - meaning comments made by users on your blog at its regular domain and comments made by users inside Facebook are all shown to users of either "view" of your content.
Facebook users can also - at their option - add a profile box to their profile, using the "add to profile" button at the top of the default canvas page.
That profile box shows the N most recent posts from your blog, as links. (N = user configurable).
WPBook also post notifications automatically to your wall, or the wall of pages for which you are an admin, to which you've added the app, and for which you've granted stream publish permission, when you write a new post.
WPBook DOES NOT (yet) do any of these: - Post notifications into your users feeds (except for your posts to your wall) when you publish a post - Post notifications back to a users feed when he/she posts a comment
If you'd like to do these things, please investigate: - Simplaris Blogcast (http://apps.facebook.com/flogblog/) - The Facebook Notes application (for fan pages) (http://www.facebook.com/notes.php) - The Sociable Facebook Connect plugin (http://www.sociable.es/facebook-connect/) - The Wordbooker Plugin (http://wordpress.org/extend/plugins/wordbooker/)
As of 1.5, this plugin requires PHP 5.
