The top 10 neighbors span six distinct subcategories — no single kind dominates — which is the defining structural fact about Inside Higher Ed's audience shape.

The shape is broad, with scores running from 0.99 down to 0.86 across a genuinely mixed neighbor set. The Chronicle of Higher Education sits at 0.99, the only neighbor that comes close to a dominant pull, and it shares the higher-education beat directly. After that, the set disperses quickly across kinds. The National Science Foundation (0.93, Research Organizations) and Times Higher Education (0.90, News Publishers) form a recognizable academic-and-research cluster at the top, joined by AP Stylebook (0.88, News Publishers) — a journalism-craft resource whose presence signals an audience with professional writing interests alongside academic ones.

The more structurally notable finding is what fills positions five through ten. NPR Science Desk (0.87) and Up First (0.87) are Podcasts and Radio, not publishers or research bodies. Then two Humor Memes and Satire accounts appear: Ladies And Gentlemen, The Weekend (0.87) and Terrible Maps (0.86). Sports Business Journal (0.86, News Publishers) and AP Oddities (0.86, Websites) round out the ten. Inside Higher Ed's own subcategory — News Publishers — accounts for three of the ten neighbors (Times Higher Education, AP Stylebook, Sports Business Journal), but the remaining seven span five other subcategories, with public-radio programming and humor accounts both registering as genuine audience neighbors.

The broad shape here reflects an audience that reads academic trade coverage but whose attention also extends across public-radio programming, science journalism, and even satirical content — a wide behavioral footprint with no single secondary cluster owning it.
