Affordances, Modes and Modalities in Shaping Cultural Memory on Social Media

Multimodal platform architectures, algorithmic curation, and visually and audiovisually saturated communication reshape contemporary regimes of cultural memory. Whereas cultural memory once relied on relatively stable institutional frameworks – museums, archives, education, and mass media – it now unfolds within hybrid digital ecosystems where institutional narratives intersect with vernacular, user-generated, and algorithmically modulated content. The locus of memory is shifting from archival stability toward dynamic, processual, networked, and increasingly individualized forms of connective and hyper-connective memory.

Within these environments, the interplay of platform affordances, semiotic modes, and perceptual modalities operates as a material-semiotic and affective infrastructure shaping what is remembered, forgotten, and circulated. The presentation highlights a shift from narrative to diagrammatic logics of memory: condensed, affectively charged, multimodal fragments facilitated by algorithmic curation often privilege immediacy and emotional salience over contextual depth. These transformations also have democratic implications, as the combined dynamics of affordances, modes, and modalities enable both participatory and expressive forms of memory activism as well as polarization, fragmentation, and antagonistic forms of memory politics.
