unfriending online?

Social networking makes it very easy to have friends these days. Hundreds of people have joined to Facebook, Twitter, Orkut and other sites so that they can communicate with their friends online. However I think the meaning of the word friend has changed. In the past, a friend was someone you had a close personal relationship with and now anyone in the world can be your friend online! Nowadays it has become so common to get rid of "friends" with just one click. There's even a new way to describe it: Unfriend ( the New Oxford American Dictionary named it the word of the year in 2009), the question I have is: why would you "unfriend" someone?
