Medium's top 10 nearest neighbors span magazines, websites, tech personalities, and authors — with no single entity pulling significantly ahead of the rest, and scores compressed between 0.99 and 0.98.
The shape is flat: WIRED leads at 0.99, followed closely by Jack Dorsey (0.99), Co.Design (0.99), Anand Giridharadas (0.99), and The Muse (0.98). No single neighbor dominates. Tallying the subcategories across the top 10 reveals a mix: Magazines (WIRED, Mashable, Fast Company), Websites (Co.Design, The Muse, Fast Co. Impact, Slate, The Verge), and Tech Personalities (Jack Dorsey, Alexis Ohanian Sr.) — with Authors (Maria Popova, Anand Giridharadas) rounding out the set. Medium's own subcategory, Websites, accounts for four of the ten neighbors, making it the most represented single subcategory, but not a majority. The cross-kind presence of tech personalities and authors alongside digital publications is the defining structural feature: this audience doesn't sort cleanly into one media type.
The flat, mixed-subcategory shape suggests Medium draws an audience whose reading and following habits cut across tech-inflected media, long-form writing, and founder-class personalities in roughly equal measure.
