Reach against resonance

Each dot is a post. Right is more views, up is a higher engagement rate. The lines are the medians, so the four corners are the four kinds of post.

@arena posts Code Arena WebDev leaderboard with 14 models

The leaderboard drew 566K views, 12x @arena's median, while its 0.62% engagement rate stayed below the AI chart median.

What happened

@arena published a Code Arena: WebDev leaderboard on September 2, 2026, showing 14 models. It was one of 6 posts from the account that day, alongside a 1.8M-view WebDev leaderboard, Agent Arena 3.8 Flash Ranked #14 at 213K, and a Pareto Frontier post at 146K.

The numbers

It reached 566K views, #141 of 1,162 AI chart posts by views and #18 of 239 @arena posts. Its score of 77 ranks #106 of 1,162 AI chart posts.

The lesson

A 14-model leaderboard drew 566K views, 12x @arena's median, but its 0.085% save rate sits below the engagement the reach would carry. The chart shows Qwen3.8-Max-0902 at 1691 and Claude Opus 5 (High) at 1688, a 3-point gap at the top.

What it means

At #6 of 239 @arena posts by score, this leaderboard is the account's strongest chart format by rank, yet its 0.62% engagement rate trails the median. The 12x views-per-follower ratio shows the format travels beyond followers without converting them to saves.
