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

Uses concrete numbers instead of vague claims, which makes it credible and quotable.
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: plain, matter-of-fact
Mechanisms: Specificity
Written for: People building with AI
