Facebook has launched a feature to let you temporarily hide annoying friends from your newsfeed. The feature, Snooze, allows you to unfollow a person, page, or group for 30 days. With Snooze, you can clear your News Feed of friends you still like, but who currently won't stop posting about their recent exotic vacation, wedding, or new cat. When their life is back to normal, you can "Unsnooze" them, and they'll be none the wiser.
