Since the proliferation of social media use in mainstream society as a means of connecting and communicating with others, postsecondary institutions have adopted social media for a myriad of purposes such as connecting with students, recruiting, and teaching. Higher education administrators are also using social media as a means of evaluating faculty productivity and scholarly impact. Through the lens of legitimacy and imposter phenomenon in the present study, we explored how social media has affected our sense of self as early career tenure-track faculty. Our collaborative autoethnography revealed the following two themes: (1) Contending with Self-Doubt and Self-Promotion as well as (2) Shifting Internal Motivation Dynamics. In addition to specific recommendations to help administrators and faculty developers promote faculty success, we also discuss areas for future research.
