Social media has long been recognized as an important domain for the usage of endangered and minoritized languages, as well as a platform for language-activist activity. Based on a decade of participant-observation in the Louisiana Creole Virtual Classroom, a revitalization community based on Facebook, this paper describes how speakers and learners of minoritized and endangered languages can form online communities for activism, resource development, learning and teaching. Louisiana Creole is critically endangered and has received little to no institutional support, but the Virtual Classroom has succeeded in creating a large number of new speakers through peer-mediated learning and the creation of learning resources. The orthography developed for the Virtual Classroom has now achieved widespread acceptance. The Virtual Classroom has thus given rise to an enduring revitalization movement with implications extending far beyond social media. Indeed, as this paper argues, scholars and practitioners should be cautious not to view online revitalization through a dichotomous lens which induces an artificial separation between the online and offline. Online language revitalization, like its offline counterpart, is underpinned by language-ideological concerns which are visible in many aspects of the Virtual Classroom’s resource development and activism.
