Why it worked

Follows a clear Hook → Context → Landing shape, so the reader always knows where they are.
Ends on a short line that is easy to quote and repeat.
Written from experience rather than as advice, which is harder to argue with.
Short enough to read in full without expanding, which removes a step before the point lands.
Short sentences keep the pace up, so the reader never has to re-read a line.

The mechanics

Hook: Announcement
Structure: Hook → Context → Landing
Style: Conversational paragraphs at a steady pace.
Tone: punchy, corporate
Written for: People building with AI
