Radiotopia's ten nearest neighbors span six distinct subcategories — podcasts and radio, authors, websites, journalists, activism, and a book publisher — with no single type dominating and scores compressed into a narrow band from 0.97 to 0.97.

The shape is flat: Radiolab leads at 0.97, followed immediately by This American Life at 0.97, but neither pulls away from the pack. Three of the top ten are fellow podcasts and radio properties — Radiolab, This American Life, and On the Media (0.97) — so Radiotopia does draw some same-kind neighbors. But the remaining seven slots belong to other subcategories entirely: authors Roxane Gay (0.97) and Jessica Valenti (0.97), journalists Ken Klippenstein (0.97) and Sam Sanders (0.97), website The A.V. Club (0.97), activist organization Planned Parenthood Action (0.97), and book publisher Timothy McSweeney (0.97). The cross-kind spread — literary authors, journalists, advocacy organizations, and culture websites sitting alongside podcast peers — is the defining structural feature here, not any single dominant neighbor.

The flat, cross-kind pattern suggests Radiotopia's audience is shaped by a coherent sensibility that cuts across media formats rather than by loyalty to any one channel type.
