Point 6 is inaccurate. As far as I know it's not a "Connection" in way they are claiming. It's a search on recent posts that appear in the "related posts" boxes. The "FBI" example is nice and scary, but the same holds true for Puppies and Rainbows.
Who can see it though? It appears that a very extended network can view certain wall posts of mine with select words, even though I've limited all my wall posts to select friends.
