If you don’t see your own fan page status updates in your news feed, make sure they aren’t “hidden.”
1) Scroll to the bottom of your news feed. (in your PROFILE, not on your Fan Page)
2) Click on “Edit Options” toward the bottom right. (click on the image to enlarge it)
3) Make sure your Fan page isn’t listed in the “Hide” box on the right. If it is, just click the “x” on the right side of it to remove it.
