AlterNet's top 10 neighbors span news publishers, magazines, activism organizations, and fellow websites — a mixed-subcategory cluster with no single dominant kind and no standout score gap between them.
Similarity here measures how closely two entities' audiences resemble each other in composition. The shape is flat: scores run from 0.97 at the top down to 0.93 at position 10, a band of less than four points across the entire set. Truthout leads at 0.97, but it does not pull away from the field the way a spike-shaped neighbor would. MoveOn (0.95) and The Nation (0.95) follow closely, then Mother Jones (0.95), Salon (0.94), and HuffPost Politics (0.93).
Tallying subcategories across the top 10: three are News Publishers (Mother Jones, HuffPost Politics, Guardian US), two are Magazines (The Nation, Salon), two are Activism organizations (MoveOn, Media Matters), two are Websites (Truthout, Daily Kos), and one is an Author (Marianne Williamson). AlterNet's own subcategory — Websites — accounts for two of the ten neighbors, so the audience is not exclusively shaped by fellow websites; it overlaps just as strongly with news publishers, magazines, and activist organizations.
The flat, compressed band of scores indicates an audience that is broadly shared across a consistent ideological-media ecosystem rather than tightly anchored to any single entity or format.
