Selfies are a reflection, I find the selfies very interesting as they reveal so much about the person behind them.
On the one hand the story they want to tell and on the other hand the hidden agenda.
Selfies are so commonly used today, people (including me :-)) are trying to position themselves as an attractive individual, interesting busy while mostly we are lonely.
We post the selfies all over the social network even when the photos are really bad and boring, and sometimes even ridicules.
We all want attention and love, the means to get it changed dramatically and I find that fascinating.
