The top 10 neighbors for This American Life span podcasts and radio, journalists, comedians, non-profits, and a book publisher — no single subcategory dominates, and the scores compress into a narrow band from 0.98 to 0.99.

The shape is flat. Ira Glass leads at 0.99, followed by Radiolab at 0.99 and ProPublica at 0.99 — but the gap between first and tenth is smaller than the gap between any two neighbors in a spike-shaped graph. Tallying the top 10 by subcategory: four are Podcasts and Radio (Radiolab, Serial, All Songs Considered, Crooked Media); two are Comedians (Jon Lovett, John Hodgman); one is a Journalist (Ira Glass); one is a Non-Profit (ProPublica); one is a Book Publisher (Timothy McSweeney); and one is Activism (Planned Parenthood Action). The mix is genuinely cross-kind: only four of the ten share This American Life's own Podcasts and Radio subcategory, while the remaining six come from five different subcategories.

What the flat shape reveals is an audience that doesn't belong to any single content type — it circulates equally across public-radio programming, investigative journalism, political comedy, and civic organizations, with no one neighbor pulling meaningfully ahead of the rest.
