Radiolab's top 10 neighbors span podcasts, journalists, book publishers, non-profits, and websites — a mixed-subcategory cluster with no single dominant kind and no score that breaks away from the pack.
The shape is flat: the highest similarity in the top 10 belongs to This American Life at 0.99, and the tenth-ranked neighbor, The A.V. Club, sits at 0.98 — a spread of less than two percentage points across the entire set. That compression means no single neighbor is structurally dominant; the audience shape is defined by the cluster as a whole rather than by any one pull.
Tallying the subcategories across the top 10: three are Podcasts and Radio — This American Life (0.99), Crooked Media (0.98), and On the Media (not in top 10 — correcting: the top 10 are This American Life, Ira Glass, Timothy McSweeney, ProPublica, Planned Parenthood Action, Atlas Obscura, Crooked Media, Planned Parenthood, Sam Sanders, and The A.V. Club). Retallying: two are Podcasts and Radio (This American Life, Crooked Media); two are Journalists (Ira Glass at 0.98, Sam Sanders at 0.98); two are Non-Profit (ProPublica at 0.98, Planned Parenthood at 0.98); one is a Book Publisher (Timothy McSweeney at 0.98); one is Activism (Planned Parenthood Action at 0.98); and one is a Website (Atlas Obscura at 0.98). That distribution — journalists, non-profits, and fellow podcasts sharing nearly equal weight — points to an audience that moves fluidly across public-radio adjacent media, investigative publishing, and civic organizations rather than clustering tightly around any single content type.
The flat shape here reflects an audience with broad, evenly distributed overlap across a recognizable ecosystem of public-interest media.
