The top 10 neighbors for The Rumpus are literary magazines, websites, and publishers — a tight cluster of editorial reading culture with scores spanning just 0.99 to 0.97, the hallmark of a flat shape with no single dominant pull.

Similarity here measures how closely two entities' audiences resemble each other in composition. Five of the ten neighbors are magazines: Electric Literature (0.99), Granta (0.98), LA Review of Books (LARB) (0.98), Harper's Magazine (0.97), and The Paris Review (0.97). Two are websites — Literary Hub (0.98) and Longreads (0.98) — and one is a book publisher: Timothy McSweeney (0.98). The Rumpus is itself a blog; the only other blog in the top 10 is The Millions at 0.98. Rounding out the set is author Jessica Valenti at 0.98 — the sole individual in an otherwise all-channel neighbor group.

The flat shape means no single neighbor stands apart structurally; the audience is defined by the cluster as a whole rather than by any one gravitational center. What the cluster describes is a literary-editorial reading audience that moves fluidly across magazines, long-form websites, and independent publishers — with no meaningful gap between the nearest and tenth-nearest neighbor.
