As you’ve no doubt heard, Facebook rolled out some major changes this week—and even bigger changes will be hitting your Wall in the weeks to come. (More on those in a minute.) Many Facebook users were caught off guard by the new “ticker” that now appears in the upper right corner of the News Feed page. The ticker is a sort of mini-news-feed, designed for what Facebook CEO Mark Zuckerberg calls “lighter weight” information. It’s a constantly refreshing scroll of your friends’ comments, likes, and other Facebook activity, magnetically pulling your gaze over and over again.
Here’s a really important thing to know: if you comment on a friend’s status update, the privacy level of your comment is determined by whatever sharing setting your friend chose for that update: public, friends-of-friends, friends only, or a customized group. This has always been the case—the difference now is that your comments are popping up in your friends’ tickers, and they’re much more noticeable than in the news feed. If you leave a comment on an update with a “friends of friends” setting, that comment will appear in your friends’ tickers, even if your other friends don’t know the person whose update you’ve commented on.
