Facebook enables people to interact with each other, post their thoughts on their Timelines and share them with select groups of people or with all Facebook users, and share multimedia content with their friends. You can share interesting YouTube videos with specific friends by including the videos in Facebook messages. The videos can be played directly from Facebook, if they have the embedding feature turned on. If the embedding feature is turned off, the recipient must navigate to YouTube to view the video.
