The top 10 neighbors for How I Built This span news publishers, research organizations, podcasts, journalists, authors, and magazines — with no single entity pulling significantly ahead of the rest. Similarity scores run from 0.96 (Pew Research Center) down to 0.95 (Five Thirty Eight), a range of just 0.01 across the entire set.

The subcategory mix tells the clearest story. News publishers account for three neighbors — Axios (0.96), STAT (0.96), and The Upshot (0.95) — while journalists contribute two: Nate Cohn (0.96) and Nate Silver (0.95, via his journalist subcategory). Research organizations appear twice — Pew Research Center (0.96) and Brookings Institute (0.95). Rounding out the ten are NPR's Planet Money (0.96), the only fellow podcast in the top 10; The Lancet (0.95), a magazine; 538 Politics (0.95), a blog; and Ed Yong (0.95), an author. This is a cross-kind cluster: the center entity is a podcast, yet most of its nearest audiences belong to data-driven news outlets, policy research organizations, and analytical journalists — not other podcasts.

The flat shape and compressed score range indicate an audience that distributes evenly across a broad, editorially serious neighborhood rather than concentrating around any single peer.
