Upworthy's top 10 nearest neighbors span journalists, activists, non-profits, news publishers, and fellow websites — a mixed cluster with no single subcategory dominating and scores compressed into a narrow band from 0.97 to 0.97.
The shape is flat: the spread across the top 10 runs only from Slate at 0.98 down to Salon at 0.97, with Padma Lakshmi (0.98, TV Personalities), ProPublica (0.98, Non-Profit), Anand Giridharadas (0.97, Authors), Indivisible Guide (0.97, Activism), and Michelle Wolf (0.97, Comedians) all clustered within hundredths of one another. No single neighbor pulls away from the pack. Tallying the top 10 by subcategory: Websites (Slate, Medium), News Publishers (Mother Jones), Magazines (Salon), Non-Profit (ProPublica), Activism (Indivisible Guide), TV Personalities (Padma Lakshmi), Authors (Anand Giridharadas), Comedians (Michelle Wolf), and Technology (Squarespace) — nine different subcategories across ten neighbors. Only two neighbors share Upworthy's own subcategory (Websites): Medium at 0.97 and Slate at 0.98. The rest are drawn from across journalism, civil society, and entertainment.
What the flat shape reveals is that Upworthy's audience is not defined by affinity to a single content type or institution — it is shaped by a broad, cross-kind cluster of progressive media, civic organizations, and individual voices that all draw from the same underlying audience pool.
