Previous research incorporates Habermas’ theory of communicative action with implications of social media for public discourse, yet few studies consider the theory’s relevance and applicability to public administrators. This article addresses this weak link by focusing on the administration legitimacy dilemma. While social media can be useful to public administrators facilitating collaborative interactions with citizens, these platforms are not automatically suited to public participation in governance. Habermas’ theory offers a framework for understanding these possibilities and challenges, as well as adapting social media constructively to administrative practice.
