The top 10 neighbors for On the Media are journalists, print magazines, and literary media — not other podcasts or radio programs. Similarity here measures how closely two entities' audiences resemble each other in composition; a score near 1.0 indicates near-identical audience shape.

Four of the ten neighbors are journalists: Astead Herndon (0.98), Jamelle Bouie (0.98), Lauren Duca (0.98), and Rebecca Traister (0.98). Two are magazines — CJR (0.99) and The New Republic (0.98) — and the remaining four span an author (Jessica Valenti, 0.99), a long-form reading site (Longreads, 0.99), a book publisher (Timothy McSweeney, 0.99), and an activist (Gloria Steinem, 0.98). No other podcast or radio program appears in the top 10.

The scores compress into a narrow band — 0.98 to 0.99 — which is the defining feature of a flat shape: no single neighbor pulls away from the rest. What the cluster does reveal is that On the Media's audience is shaped primarily by print journalism and literary culture rather than by audio media. The presence of CJR, a publication focused on press criticism, alongside individual journalists and literary magazines points to an audience that follows media as a subject, not just a format.

This is an audience defined by its relationship to journalism and the written word, regardless of the medium it arrives through.
