Web 2.0. is a space for communication and exchange, a place of writing that contributes to transforming “ a former society based on written sources into a society of writing" (Petitjean 2016:97- freely translated from French). Digital writing has been gradually integrated into classroom practices, particularly in language classrooms, as evidenced by didactic research (Desmet & Rivens Mompean, 2010; Moore & Molinié, 2012). This work shows that foreign language teachers are trying to take these new ways of producing the written word into account in order to develop learners' communicative language skills. Multimedia projects such as these promote interactions that generate social ties and the development of collaborative strategies. In this project, we are interested in how digital environment resources enable learners' language activities to make sense in social actions, through interactions on the BIEN! blog between the universities of Lille and Louvain-la-Neuve (Rosen, 2017). In this article, we want to analyze the "Commentary" productions by adopting the multi-modal media literacy paradigm (Lebrun & Lacelle, 2014) and focusing on the hybridity of posted messages.
