The top 10 neighbors for Talking Points Memo compress into a narrow band — scores running from 0.9866 down to 0.9803 — with no single neighbor pulling away from the rest. That tight clustering is the defining structural fact here.
Eight of the ten neighbors are journalists: Ezra Klein (0.99), Ari Berman (0.99), Ana Marie Cox (0.98), Adam Serwer (0.98), Dave Weigel (0.98), Yashar Ali (0.98), Josh Marshall (0.98), and Matthew Yglesias (0.98) — all classified as Journalists under Celebrities and Influencers. The remaining two are Slate (0.98), a Website, and Jonathan Martin (0.98), also a Journalist, tied with Indivisible Guide (0.98), an Activism organization. That makes nine of the top ten neighbors Journalists, with Slate the lone non-journalist individual in the set. No other News Publisher appears in the top 10 — Talking Points Memo's own subcategory is absent from its nearest neighbors entirely.
The pattern is a dense journalist cluster: the audience that reads TPM looks almost identical to the audiences that follow individual political reporters and commentators, rather than other news outlets. The one Activism entry and the one Website sit at the same similarity level as the journalists, suggesting no meaningful separation between those categories within this neighborhood.
This shape reflects an audience defined less by outlet loyalty than by engagement with a specific stratum of political journalism as a whole.
