I enjoyed this article until they started focusing on "selfies" and social media. Loneliness and human interaction over the internet is a very interesting subject but I feel like the author has only used facebook and instagram.
There is no reason to limit this topic to communication platforms built upon exposing your own personal life and connection that with you communication.
I think that communication over IRC, blogs, reddit, comments like this and chans are more "pure" in a way and more interesting.
