Abstract
The rise of social media has fundamentally reshaped the public sphere, altering how individuals access information, engage in debate, and participate in democratic processes. While digital platforms provide unprecedented opportunities for inclusivity and global dialogue, they also generate new challenges, including polarization, misinformation, and the concentration of communicative power in corporate hands. This paper explores the digital public sphere through an anthropological and sociological lens, examining how online networks influence identity, discourse, and political participation. Social media creates spaces for marginalized voices but simultaneously fosters echo chambers that fragment societies. Polarization, driven by algorithms and selective exposure, undermines democratic deliberation by deepening ideological divides. Furthermore, the commodification of attention and the spread of misinformation threaten the credibility of democratic communication. The paper argues that the digital public sphere embodies both democratic promise and peril. Understanding its dynamics is essential for reimagining inclusive and resilient democratic practices in the 21st century.
