The cascade's content multiplier: one core piece (game accessibility article) multiplied across four platforms (Substack deep dive, YouTube visual demo, Twitter thread, GitLab technical resources). Each platform reaches different audiences with content optimized for that platform's format. The multiplier effect means total reach exceeds the sum of individual platform audiences because of cross-platform discovery. A Twitter user finds the Substack; a YouTube viewer finds the GitLab. The network effect amplifies the initial content investment.
