This research concerns linguistics, language and culture didactics and information and communication technologies. It considers human and social dimension as being at the heart of the information society; social networking is obviously predominant nowadays and concerns language didactics and French as a foreign language. This empirical research concerns remote mediated writing interactions and aims to explore the special characteristics of this new way of interactive writing which emerges from online interactions. What kind of social and discursive practices social actors implement during remote mediated writing interactions? Based on a double data of written mediated interactions (natural online context and pedagogical online context), our study aims to provide new elements concerning virtual sociodiscursive writing. We are paying particular attention to the different characteristics of virtual mediated writing (linguistics, semio-linguistics, interactional and discursive) social actors are using to act and communicate in a virtual environment. By means of a multidisciplinary approach (speech analysis, conversational analysis based on ethnomethodic and Goffman's interactionism) we have tried to identify the particularities of virtual sociodiscursive writing contributing to better learning.
