The advent of the social media revolution in contemporary time has had a phenomenal impact in almost every area of human endeavor in many societies. However, social media has some credibility burden that could hinder its effective use and also produce unintended consequences such as political propaganda, and other unwholesome activities as it affects politics and governance. This study sought to assess the nexus between social media, political scandal and good governance in Nigeria. It also assessed the success or otherwise of the institutional counter-measures in checkmating the excesses of social media. Situated within the framework of reputation repair and social responsibility theories, the paper acknowledges that the conventional mass media has ties with the political and economic forces in the society, thus, are somewhat incapacitated in rising to the societal challenges. Consequently, the paper presents the social media as a veritable alternative, arguing that social media tools have what it takes to serve as a platform for citizen participation in governance.
