Facebook announced at SXSW that more than 1 billion instances of application activity are now shared daily on Facebook. Also, more than 400 billion Open Graph actions have been shared back to Facebook as of this month. Facebook defines this open graph activity as high-level "interactions" users can perform within your app (commonly follow, like, listen, reading an article and watching a video). Some familiar open graph actions shared on your timeline for example would be pins added to Pinterest, or a new post on Tumblr. via AFP/Getty Images
Facebook's development team has also shared that as of March 2013, "110 million songs, albums and radio stations have been played 40 billion times" via Facebook-integrated apps and "1.47 million books have been shared." Facebook stated that "on average, people choose to share their app activity" which is mounting up to over 1 billion times daily. In fact, many users have opted-into sharing their activity from apps automatically either unknowingly or to just save time. So these stats should be very intriguing to developers looking to take advantage of using the open graph within their applications to boost virality.
