Facebook Mixes Your Friends' Walls Into Your News Feed
It's not been officially announced from Facebook yet, but just today I started to get updates in my News Feed from my friends who make comments on the wall of another of my common friends.
The same feature is available for Facebook Group. You only will see stories when one of your friends posts within a group rather than when all members post.
For example, you will see a story when your friend uploads photos from a recent party at your high school alumni group or when one of your friends posts a message on the Wall of Soccer group saying that "there is a special game this week", then that message appear in your news feed. Remember you're able to see the updates only from the friends which are part of the same group.
Until now, this feature was only limited to Facebook Group. but it seems that Facebook pushed the feature in profiles also.
I think this is a great way to keep up with friends where you can see wall to wall communication of your common friends. It seems that this changes is limited to some people. If you do not see it in your News Feed yet, check back soon.
