This study examines an ethnographically-collected set of social media posts from 5 applications in order to understand the rhetorical functions of something we call "metacommunicative" hashtags (e.g., #PackersGottaWinThisOne, #thisweddingisawesome). Through a process of inductive analysis, we identified recurring genre functions that are both context-specific to applications' ecologies and, at the same time, "stabilized enough" (Schryer, 1993, p. 204) to warrant the use of rhetorical genre theory as a tool for understanding their communicative purposes
Daer et al. (2015) studied this question.
