The nature of communicative practices today, particularly in the context of digitalized media, has revealed that earlier paradigms on language contact do not prove to be fully satisfactory. Based on 1,507 Facebook posts of German university students participating in the Erasmus exchange program, the analysis aims at exploring how posters draw on their entire repertoire of local and «translocal» semiotic resources in interactions among speakers with diverse language backgrounds. The students under examination participate in actual processes of meaning-making by refashioning the semiotic potential of various features. As a result, the interlocutors create heteroglossic and polycentric posts to decollapse collided and fuzzy contexts and to negotiate potentially large and multiple audiences.
