Digg and Facebook can be considered famous web2.0 sites abroad, and the domestic copycats Diglog and Xiaonei.com also have a large daily volume of visits. A few days ago, Shuil once wrote about the recommended song: Gotta digg (Digg website song, with mp3 download). As for Facebook, Digg's counterpart, it naturally has its own site song as well. Indeed, there is a video on YouTube named Facebook Anthem (Hymn ~!~). Unlike Gotta digg, this hymn is actually a satire of Facebook.
