Kraft Mac & Cheese Thanks Facebook Fans

Kraft Macaroni & Cheese hired an a capella group to show appreciation for the 4,632 fans who "liked" its Facebook page. Sung by The Yellow Jackets from the University of Rochester, the song is a great example of connecting with customers in a creative way.

The video is cute, but so far it has only 11,000 views after a week. Why hasn't it been more popular? Will it go viral still?
