The notion of common ground entails that prior to a conversation, mutually shared knowledge is available to interlocutors by virtue of the situational context or a shared cultural background. Within linguistic pragmatic theories, recipient design is a determining factor for cooperation in interaction. The socio-cognitive approach to communicative interaction acknowledges the importance of cooperation and common ground but maintains that interlocutors tend to adhere to their individual background knowledge and experience for production and comprehension. The shared knowledge base may therefore not be fully available prior to the exchange but, rather, established dynamically and interactively in the course of the conversation. Discussing internet memes, it will be shown that stable core common ground and dynamic emergent common ground are fundamental assets for the description of contemporary and future phenomena in digital communication. I will argue that internet memes represent a kind of communication where emergent common ground is aspired to rather than resorted to as an emergency solution when core common ground is lacking.
