摘要	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.	Comparative case study is a qualitative research design in which two or more bounded cases are studied in depth and then systematically compared to identify similarities, differences, and patterns across contexts. Rooted in Yin's replication logic and Stake's multiple case framework, it is particularly suited to questions that ask how or why a phenomenon unfolds differently — or similarly — across distinct settings, populations, or time periods.	Netnography is a qualitative research method that adapts the principles of cultural ethnography to the study of online communities and social media environments. Coined by Robert Kozinets in 1997 and systematised in his 2010 handbook, netnography treats digital spaces — forums, social networks, blogs, review sites — as naturally occurring field sites where communities gather, share meanings, and construct identities. The method combines unobtrusive observation of digital traces with active participation and, where appropriate, direct member interaction.
