概要	Digital Constructivist Grounded Theory (Digital CGT) applies Kathy Charmaz's constructivist variant of grounded theory to data generated in digital environments — social media platforms, online communities, forums, digital interviews, and other internet-mediated spaces. It treats meaning as co-constructed between researcher and participant in digitally-mediated contexts, and generates theory grounded in how people make sense of experience through and within digital life.	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.
