Seven of Product Hunt's ten nearest neighbors are other websites, and the scores separating them span barely 0.015 — from AngelList at 0.98 down to TechCrunch at 0.97. That compression is the defining feature of this audience shape: no single neighbor pulls away from the pack.

The cluster is tech-media and startup infrastructure, almost entirely. The website subcategory dominates: Hacker News (0.98), The Verge (0.97), Recode (0.97), Medium (0.97), and Techmeme (0.97) all sit within a few hundredths of each other. The three exceptions are Jack Dorsey (Tech Personalities, 0.97), Stripe (Technology brand, 0.97), and IDEO (B2B brand, 0.97) — each a different kind of entity, but all landing at essentially the same similarity level as the website neighbors. No single outlier, no structural gap: the top 10 form a dense, undifferentiated band.

The flat shape here reflects an audience that is deeply embedded in one ecosystem — startup and tech media — where many adjacent entities draw nearly identical crowds.
