By default, Facebook has your Wall set to only display posts on your Wall from Friends and Pages that you interact with most. Unfortunately, you might be missing posts from people or pages that you care about, by thinking that they just have nothing to say. Here’s how to change this. (Note: This will not make changes to the friends and pages that you have chosen to hide from your wall).
1. Go to Facebook and login to your account.
2. Go to the bottom of the Home page (the very bottom, it may take more than one try as the page continues to populate the posts on your wall).
3. Select Edit Options.
4. Click the Show posts from dropdown and select All of your friends and pages.
5. Click the Save button.
