X / Twitter Public Discourse Platform (2006)

Class card for Twitter / X, the DM-Day real-time public-discourse platform founded March 21 2006 by Jack Dorsey, Biz Stone, Ev Williams, and Noah Glass as an Odeo podcasting company pivot. Dorsey's first tweet: "just setting up my twttr." 140-character limit; @-mention and #-hashtag conventions emerged from user practice and were later formalized. The platform operated as the canonical DM-Day real-time public discourse machine — the OPP for breaking-news distribution, political direct-address (@realDonaldTrump), and public-figure signaling — through three distinct operational phases: (1) DM-Day-early 2006-2013: founding to IPO (Nov 7 2013; $26/share → $44.90 close). Arab Spring 2010-2011 + Iranian protests 2009 ("Twitter Revolution" narrative, later contested by Morozov). 140-char norm establishes the real-time public-discourse OPP; journalists + politicians adopt as primary announcement channel. (2) DM-Day-mid 2013-2022: Trump-era political amplification (@realDonaldTrump 2015-2021); mass misinformation debates; deplatforming controversies; Trump permanently suspended Jan 8 2021 (post-Capitol insurrection). Platform serves as canonical political-signal substrate. (3) DM-Day-late 2022-2026: Elon Musk $44B acquisition announced Apr 25 2022 → closed Oct 27 2022. Mass layoffs Oct-Dec 2022 (~75% workforce). Rebrand to X July 23 2023. Ad-revenue decline ~50%+ (advertiser flight post-content-moderation rollback). Twitter Blue → X Premium subscription. Mass user flight: Bluesky (~25M users Jan 2025; Jay Graber CEO; AT Protocol), Mastodon (~10M; Eugen Rochko 2016; ActivityPub), Meta Threads (July 5 2023; ~300M users 2024). X valued ~$10B by 2024 (vs. $44B purchase price). The energetic-zombie pathology is canonical: X retains structural necessity for journalists and government signal-monitoring (still used) but evolutionary intelligence is hollowed — capture_resistance VERY LOW, moderation rollback, advertiser crisis, user flight. Platform has been converted from a public-discourse commons OPP into an ideological vehicle for its owner's political and commercial interests (post-2022). dm_current = late_modernity (energetic_zombie): massive residual structural dependency by legacy institutions + govts, declining evolutionary fitness. motor=push (DM canonical; real-time public-discourse push to each user independent of user telos; no behavioral-prediction flywheel at Meta depth).
