Facebook allowed user to display new posts on your blog. Here’s how to do it:

  1. Go to your profile, and click on More under Applications.
  2. Click on Notes. Under My Notes, on the right-hand side, there is a link that says Edit settings. Click on that.
  3. Add your blog RSS feed to your settings.

Now, every time you update your blog, the post appears in your Notes, and your facebook friends will see it.
