The top 10 neighbors for NPR's Planet Money span journalists, politicians, podcasts, blogs, and a research organization — with no single entity pulling far ahead of the rest. Similarity scores run from 0.98 at the top to 0.98 at the bottom, a band so compressed it confirms the flat shape: this is a cluster, not a hierarchy.

Tallying the subcategories across the top 10 reveals a mix dominated by journalists and political media. Nate Silver (0.98) and Ezra Klein (0.98) are both Journalists; Jon Favreau (0.98) is classified as a Professional; Dan Pfeiffer (0.98) and Tommy Vietor (0.98) are Politicians. On the channel side, FiveThirtyEight (0.98) is a Website, Pod Save America (0.98) and Crooked Media (0.98) are fellow Podcasts and Radio, 538 Politics (0.98) is a Blog, and ProPublica (0.98) is a Non-Profit. Only two of the ten share Planet Money's own subcategory of Podcasts and Radio — the audience shape is defined less by podcast listeners broadly than by a specific orbit of political journalism, data-driven analysis, and civic media.

That tight cross-kind cluster — journalists, political podcasts, and data outlets all scoring within a fraction of each other — points to an audience that moves fluidly across formats but stays within a coherent media world.
