3. Facebook's New Ticker
On the right side of your News Feed you'll see a new element--the ticker--which is a stream of what's happening on Facebook in real-time. Updates in this stream include status updates, friendships, photos, videos, links, likes, apps and games activity and comments.
The ticker shares the right-hand column of your browser with Chat. While you can't close the ticker, you can make it smaller by sliding the bar between the ticker and chat, though this feature is contingent on the size of your browser.
Sliding the bar up will make the ticker smaller and Chat larger; sliding it down will make ticker larger and chat smaller. Clicking on an item in the ticker will expand it to display more information.
If you want to see fewer stories or fewer types of stories in the ticker, you can click the drop-down menu in the top right of a story and click "Hide story." Do note that every time you use the hide and unsubscribe settings to control what you see in your News Feed, it will also impact what you see in the ticker. For example, if you unsubscribed from a friend's posts via your News Feed, they will also be unsubscribed from the ticker.
4. How Your Privacy Settings Are Affected
Facebook says that the new News Feed and the ticker do not affect your privacy settings. Ticker will only display information that you're already able to see anywhere else on Facebook. Facebook does say, however, that if you start seeing stories that you haven't noticed before, it's likely because "ticker makes things easier to discover. It doesn't mean that privacy around Facebook has changed."
To control who sees your posts in the News Feed and ticker, be sure you use the privacy control in the Update Status box. Also remember that the comment privacy is tied to the privacy of the post: If you comment on someone's public post, your comment is thereby also public.
If you play games like FarmVille or use apps, Facebook publishes your activity to the News Feed and ticker. To control what apps or games information shows up in the ticker, you need to visit the privacy preferences in your Application Settings. Here, you can set the individual settings for each application by clicking "Edit" next to the application's name.
