If you (like me) have noticed that your news feed items are getting stale and you’re only getting items from the same people, click on Most Recent to reveal the drop down then select Edit Options. From here you should be able to make the change to show what everyone’s been saying. It’s a cool feature to ensure that you can stay in the loop with everyone or just opt-in to those whom you frequently interact with. If neither work for you, you can always clean your list.
