Viral score

Based on absolute engagement — the platform doesn’t expose follower counts here, so large accounts score higher.

From likes, comments.

Why it worked

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.

The mechanics

Hook: Announcement
Structure: Hook
Style: Conversational paragraphs at a steady pace.
Tone: corporate
Written for: Founders, marketers and operators
