The purpose of this research is to examine the shared governance of an online creation community using the Institutional Analysis and Development (IAD) Framework. This investigation is a case study of an intra-district Twitter Edchat, an open group of educators who meet monthly to post professional knowledge and resources about a topic. This study includes content analysis of the archived Twitter posts and Edchat documents from November 2014 through May 2017 and interviews with six active Edchat participants. The findings provide four tenets of governance required to promote novel professional knowledge and resource contributions: open boundaries, flexible participation, inclusive information available, and interactions that generate fresh perspectives to fulfill the desire to support others and learn. Further, the results indicate that Edchats thrive when the locus of leadership is within the community itself, rather than from outside, overseeing entities. Overall, this study contributes to the literature by identifying how shared governance sustains viable Edchats and other online creation communities.
