There is this exciting Facebook app that post your blog updates automatically to your Facebook wall, the NetworkedBlogs ( you can see the sample below). I had joined NetworkedBlogsfor I guess two years now but I do not write something about it because it announces that due to some changes in Facebook, it may stop updating your wall. Good thing that the app is still working now.
All you have to do is to register your blog and allow the app to publish all updates in your wall and there it goes.
You may also invite your friends to follow your blog and they will be receiving such updates too in their wall.
