Facebook, the popular networking site, has 350 million members worldwide who, collectively, spend 10 billion minutes there every day, checking in with friends, writing on people's electronic walls, clicking through photos and generally keeping pace with the drift of their social world. Make that 9.9 billion and change.

Some students even posted that particular status themselves. Facebook has become the biggest distraction for students when trying to get homework done.

Good for papers that include both the social media and music.
