Social media has its place; keeping people connected, but for some it becomes an addiction. In a recent survey of almost 25,000 people, social media addiction was associated with lower levels of self-esteem and higher levels of narcissism (excessive interest and admiration for oneself ). Social media is ego boosting and so appeals to the narcissist. The lack of face-to-face interaction may appeal to those with low self-esteem.
Getting a boost from likes and tweets is not a problem in itself however when one starts to crave the feedback, it's time to reassess !
