Rewrite for each format — don't copy-paste across mediums, because each requires different cognitive packaging for its audience

Why This Is a Rule

Marshall McLuhan's insight — "the medium is the message" — applies directly to content repurposing. A blog post copy-pasted into a tweet thread fails because Twitter demands compression, hooks, and thread-native structure. A presentation copy-pasted into a document fails because documents demand linear argument flow while presentations use visual anchoring and bullet-point cadence. Each format has its own cognitive packaging requirements: the way information must be structured, sequenced, and styled to match how the audience processes information in that medium.

Copy-paste repurposing treats content as format-independent — as if the same words serve equally well in every container. But readers on Twitter scan differently than readers of a blog, who read differently than recipients of an email, who engage differently than attendees of a presentation. Each context creates different attention patterns, reading speeds, expectation frames, and tolerance for length. Content that ignores these patterns feels "off" even when the words are technically correct — like a formal speech read aloud at a casual dinner.

The rewrite doesn't change the ideas — those remain constant across formats. It changes the packaging: sentence length, paragraph structure, emphasis placement, level of detail, opening hook, closing action. The ideas are the invariant; the packaging is the variable that must adapt to each medium.

When This Fires

• When repurposing content from one format to another (blog → social, presentation → document, report → email)
• When cross-posted content consistently underperforms native content on a platform
• When Define the distribution plan before starting production — audience, channels, format, and timing are design constraints, not afterthoughts's distribution plan identifies multiple channels requiring different formats
• Complements Cascade derivative formats over days/weeks after the pillar ships — extend content life, prevent fatigue, create multiple touchpoints (cascade release timing) with the format-adaptation quality standard

Common Failure Mode

The cross-post: taking a LinkedIn post and posting it verbatim on Twitter, an internal wiki, and a newsletter. The LinkedIn post was optimized for LinkedIn's algorithm, audience, and reading context. On Twitter it's too long. On the wiki it lacks context. In the newsletter it misses the personal tone. Same words, four failures.

The Protocol

(1) When repurposing content, start from the core idea, not the existing text. Summarize the idea in one sentence. (2) For the target format, ask: "How does this audience consume content here? What attention span do they have? What structure does this format expect? What tone matches?" (3) Rewrite from the core idea to match the target format's requirements: adjust length, restructure for the medium's flow, adapt tone, and change emphasis to match what this audience cares about. (4) The rewrite should feel native to the target format — a reader shouldn't be able to tell it was originally created for a different medium. (5) Keep the core idea identical across all formats. The packaging changes; the insight doesn't.
