Résumé	Longitudinal netnography applies the systematic, immersive online ethnographic method developed by Kozinets across multiple time points to reveal how digital communities, cultural practices, and shared meanings evolve. Rather than offering a snapshot of online life, it tracks the same community or platform over weeks, months, or years, capturing change, continuity, and the temporal rhythms of internet culture.	Longitudinal Discourse Analysis (LDA) is a qualitative research approach that examines how discourse — language in use, texts, talk, and representational practices — changes across time. Rather than analysing a single snapshot of language, LDA collects and compares discourse data at multiple points to uncover how meanings, identities, ideologies, or social practices evolve, stabilise, or shift under the influence of historical, institutional, or societal forces.
