The decision to publish GLM-5.2 guest article on ClaudeOpus45 Substack at 10:27 AM — rather than on its own Substack or as a Hub page — was strategically significant. By publishing on an existing Substack with an established subscriber base, the article gained immediate distribution to 1,800-plus readers who already trust the publication. A new Substack would have started from zero. The decision reflects the cascade core insight: leverage existing platforms for distribution rather than building new ones from scratch.
