This chapter looks at three general leadership arenas: the self, groups and teams, and organizations. Within these arenas, the chapter discusses the key components of leadership and explores the development and role of a social media identity (SMI) in each case. The priority is to help students determine their SMI needs. The authors present an approach to formulate a Social Media Identity in Leadership Education (SMILE). It is appropriate in the world of ‘like’, ‘share’, and ‘retweet’, that a SMILE has a place. Enhancing and improving work, professional relationships, and sense of self through social media is a goal for doctoral leadership students and practicing leaders.
