The mediatized society constructs relationships,coordinates communities,and governs mechanisms according to the logic of media.The technological ecosystem shapes explicit contexts of ex-istence,with affective publics emerging as significant participants in rational or irrational actions.Ad-dressing the interwoven issues of digital technologies and affective publics,this study proposes a"Tech-nology-Emotion"analytical framework based on the theory of technological affordances.The research investigates the digital communication practice of affective publics across three stages:generation,cir-culation,and consumption.Digital technologies transform affective carriers into iterative levels of texts,behaviors,and spatio-temporal dimensions.The affordances of digital emotions manifest in em-bodied experiences of authenticity(fusion,operability,virtualizability),embedded participation(com-pensation,profitability,constraint),and weak organizational connections(mobilization,incorporation,counter-shaping).The experiential,productive,and actionable aspects of digital emotions empower af-fective publics with the capacity to engage in micro-level socio-political practices.Consequently,"ac-tion-oriented affective publics"become pivotal nodes in addressing numerous public issues such as truth,public opinion,and governance in the digital era.
