This is one in a series of books from PowerReviews eBooks: “It’s simple. Facebook is continuously releasing new features that encourage sharing. Take a look at the graph below [which appears in the eBook) for a glimpse at the sharing growth. Overlayed on top of the graph are icons for the various features Facebook has introduced over the years. In 2004, all you could share was your profile information. The volume of sharing was much lower: roughly 0.1 pieces of content per day per person. Today, according to Facebook, that number is well over 30 times that. As Facebook has introduced such things as photo albums, the news feed, messaging and the like button, the volume of sharing has gone up. Facebook is making it easier for us to share everyday with new features that remove barriers to sharing content. As a result, we’re seeing exponential growth in the volume of content being shared.”
