In the context of intelligent media,the role of the social media platform gatekeeper is evolving from a traditional filter to an interactive one,involving users,editors,and machines.This shift introduces a coordination problem among the various subjects behind the mechanism.The tension between the polysemy of Chinese characters,creative users,and the logic of a singular machine creates communication barriers,highlighting the value conflicts and relational tensions between"human-machine"and"human-technology."The research reveals that the technical order,dependency on technology,and the"technical laws"arising from the intervention of intelligent machines constrain users'independent expression,undermine the professional role of editors,hinder emotional communication across different circles and groups,and contribute to the solidification of thinking,misjudgment of content,and the spread of"typos."To address these challenges,the paper suggests reconstructing subject relationships through the lens of intersubjectivity theory,finding a balance between technological rationality and humanistic concern,and promoting collaborative governance among multiple subjects.This approach will help foster the healthy development of the platform's content ecosystem.
