I have been traveling for the past few weeks and dealing with family issues, so I am only just getting around to posting about this, from me in PJ Media on May 14:
Selfies did not cause the phenomenon of the purely Internet-based relationship. Those were around before selfies became common. (I believe such relationships started during the age of AOL Instant Messenger and got worse from there.) In my experience, most selfies are not sent to an interlocutor directly, but posted passively on social media profiles. When the recipient is a specific somebody, selfies can enhance the humanness and intimacy of an online encounter. When the recipient is “everyone,” however, I think this is where the narcissism comes into play.
