Why does the author quote Keith Hampton? What is the purpose for including his views?

To provide the alternative perspective that social networks may be more helpful than harmful.

Explanation:

In the article written by a media outlet on November 8, 2011, two points of view are contrasted on the negative/positive aspects of social media networks. The first was that of Matthew Brashears who highlighted the fact that people were having fewer real friends whom they can go to for help even though they had a large friend base on social networks.

Keith Hampton, however, highlighted the positive aspects of social networks which he believed was healthy for us. One of them was that people had more social support than they would have had offline.
