Remember last September when Facebook announced all those changes to individual profiles, including the timeline? One of the changes was that your friends and fans can do more than “Like” or “Comment” on Facebook. Three new actions were announced at the time, including: Read, Watch, Listen to help people better understand what their friends are doing online. Facebook called it the “Open Graph” and the pr people called “A revolution to the whole meaning of listening to music together or family T.V.” You can read more about how it works from the Facebook developer notes.
