Meta's ellipsoid fit chart draws wide but thin engagement

An annotated chart on ellipsoid fit thresholds reached 95.2K views but a 0.19% engagement rate.

What happened

Meta posted an annotated chart on high-dimensional ellipsoid fit threshold on October 2, 2026. It was one of 2 Meta posts that day; the other covered Exact vs Not Exact Set Relaxations.

The numbers

The post drew 95.2K views, ranking #388 of 1,162 AI chart posts. Its engagement rate of 0.19% ranked #1,116 of 1,162, and its score of 44 ranked #701 of 1,162.

The lesson

A single annotated chart with 95.2K views but a 0.19% engagement rate shows reach does not convert to interaction. The save rate of 0.050% is below the AI median engagement rate of 0.73%.

What it means

For Meta, this post's views are 2.6x its median of 36.4K, but its engagement rate is below its own median of 0.81%. Wide reach with thin engagement marks a gap between visibility and interaction.
