I don't think I have issues presenting myself, but just in case, I can count on my family and friends (not contacts) to tell me to put my feet on the ground. I think that in social networks,  body language is disguised, so people often use emoticons/texts that don't resemble a true emotion.
Therefore, nonverbal communication on websites allows users to  control the way they want to be perceived, on a certain moment.
