On Point's top 10 nearest neighbors split across three subcategories — Podcasts and Radio, Journalists, and a pair of outliers — with no single neighbor pulling far ahead of the rest. Similarity scores run from 0.9561 (Fresh Air) down to 0.9466 (Morning Edition), a span of less than a point, which is the defining feature of a flat shape.
Four of the ten neighbors are Podcasts and Radio: Fresh Air (0.9561), The On Being Project (0.9498), Here & Now (0.9492), and Morning Edition (0.9466). Three are Journalists: Tamara Keith (0.9528), Charles P. Pierce (0.9521), and Nina Totenberg (0.9515). The remaining two — NPR Books (0.9558, News Publishers) and Lawfare (0.9475, Blogs) — sit just outside those clusters, while Everytown (0.9487, Activism) is the one neighbor drawn from outside media entirely. The journalist and podcast-and-radio neighbors are tightly interleaved by score, suggesting the audience doesn't sort cleanly between the two kinds.
The flat distribution across this mix of radio programs, individual journalists, and civic media points to an audience that moves fluidly through a connected public-affairs ecosystem rather than anchoring to any single format or voice.
