What it is and the problem it solves
Social media is a sequence of interoperable communication layers built atop earlier networks. It solves the problem of persistent, searchable, identity-linked exchange across distance—but only after decades of decentralised experimentation, not as a designed system.
How it works
Social media works by layering communication protocols with identity and connection models: PLATO (1960) introduced access-controlled message forums and chat rooms; ARPANET (1969) enabled distributed, non-institutional messaging by the late 1970s; Usenet (1980) added open, topic-based newsgroups; BBS systems (from 1973) enabled local dial-up communities; the World Wide Web (1991) unified hypertext with networked content; and SixDegrees.com (mid-1990s) imposed real-name profiles, friends lists, and school affiliations onto that infrastructure.
What works
What works is the modular inheritance: Usenet’s threading survives in Reddit; PLATO’s Notes foreshadowed wikis and comment sections; BBS file-sharing prefigured cloud storage; SixDegrees.com’s friends list became the atomic unit of Facebook and LinkedIn. Each layer remains functional when isolated—proof that social media is not one invention but a stack.
What does not
It does not solve anonymity versus accountability. It does not eliminate gatekeeping—it relocates it from editors and sysops to algorithms and platform owners. It does not scale trust: SixDegrees.com’s real-name model failed commercially, and later platforms reintroduced pseudonymity, moderation bottlenecks, and opaque access controls.
What it changes
It changes who holds the log: from university mainframes (PLATO), to military-academic networks (ARPANET), to volunteer-run servers (Usenet, BBS), to corporate-owned web services (Classmates.com, SixDegrees.com). That shift transfers editorial authority, moderation responsibility, and data ownership—without resolving how those functions should be governed.
Is it worth your time
Yes—if you need to understand how digital identity, attention economies, and networked discourse emerged from incremental, non-commercial infrastructure—not from vision or venture capital.
