Facebook is one of the most popular social media platforms today. Users from all over the world log on to Facebook's app or website daily to post updates about their lives, share photos and other media with friends, and see what the other people they know have posted recently. People as young as thirteen years old can sign up for a Facebook page, but it is important to be cautious when using this and any other form of social media. Part of the All About Social Media series, All About Facebook shares the history, uses, and features of this fun and useful social media platform.
