Why it worked

Leads with a specific number, which is concrete enough to be worth a second of attention.
Uses concrete numbers instead of vague claims, which makes it credible and quotable.
Uses short lines and white space, which makes a long post feel quick to read.
Ends on a short line that is easy to quote and repeat.
The opening line stands alone, so it reads completely before the post is expanded.
Short enough to read in full without expanding, which removes a step before the point lands.

The mechanics

Hook: Leads with a number
Structure: Hook → Landing
Style: Short lines with heavy white space, built to be scanned.
