#24 - Dr. Oeldorf-Hirsch - Why do we post on social media?

Social media platforms function as complex communication tools that amplify human interaction, offering both significant benefits for connection and risks to mental well-being. Passive consumption, such as mindless scrolling, often correlates with negative psychological outcomes, whereas active engagement—posting content or initiating discussions—fosters a greater sense of agency and community. Users engage in selective self-presentation to curate their identities, though this behavior can lead to social friction when others violate personal boundaries by sharing embarrassing or out-of-context content. Furthermore, the shift of platforms like Twitter and Facebook from personal networking spaces into primary news outlets reflects a broader societal need for real-time information. While digital communication can facilitate deep personal disclosure more quickly than face-to-face interactions, it remains a mediated experience that continues to evolve alongside shifting user needs and technological affordances.
