概要	Multiple case-based digital ethnography is a qualitative research design that conducts ethnographic fieldwork across two or more purposefully selected digital sites or communities, then systematically compares findings across cases. Rooted in digital ethnography's immersive, interpretive tradition and in multiple case study logic, it reveals both site-specific practices and cross-cutting patterns in online social life. It is especially suited to questions about how similar phenomena are enacted differently across digital platforms, communities, or cultural contexts.	Comparative Digital Ethnography (CDE) is a qualitative design that applies ethnographic methods — sustained participant observation, interview, and artefact analysis — across two or more digital settings simultaneously. By systematically comparing practices, meanings, and interactions in different online environments (e.g., distinct platforms, communities, or national contexts), CDE surfaces both site-specific patterns and cross-cutting cultural logics that a single-site study would miss.
