Early utopian notions of Internet-based community as enabling transcendence of earthly governments and cultural divides manifested in the massively multiplayer online nongame platform, Second Life. However, while platform users nearly unanimously chose governance regimes based on professional management rather than democratic self-governance, one of the few democratic experiments experienced deep conflict over precisely the utopian notions it held in common. This article examines a failed merger between two experimental democratic communities in the virtual world of Second Life as an example of the general failure of internet utopianism and a specific failure to transcend distinctions in cultures of origin (the "failure of 'convivencia,'" of the title, a term reflecting a historical model chosen by one of the communities) in a common online space. Based on ethnographic fieldwork, this article will analyze a distinction between radically different, and ultimately incommensurable, discourses around governance in the merged community amid the failure of participatory, democratic models of online governance.
