The top 10 neighbors for The Millions form a tight, undifferentiated cluster — scores run from 0.99 down to 0.97 with no single standout — and the mix is almost entirely literary and editorial media, with one notable exception.
The shape is flat: Electric Literature leads at 0.99, followed by Literary Hub at 0.98 and The Rumpus at 0.98, with Granta (0.98) and LA Review of Books (0.98) close behind. Tallying the subcategories across all 10 neighbors: five are Magazines (Electric Literature, Granta, LA Review of Books, Harper's Magazine, The Paris Review), two are Websites (Literary Hub, Longreads), one is a fellow Blog (The Rumpus), and one is a Book Publisher (Farrar, Straus & Giroux at 0.97). The outlier is Gloria Steinem (0.97), an Activist — the only individual person and the only non-media entity in the top 10. The center entity's own subcategory, Blogs, appears just once in the top 10 (The Rumpus), meaning the audience shape is defined less by the blog format than by the literary-magazine and book-culture ecosystem surrounding it.
The overall picture is a densely coherent literary-media audience with essentially no gradient across the top 10 — a cluster that moves as a single bloc across magazines, literary websites, and book publishers.
