Viral content spreads via concentrated network hubs, not person-to-person chains

Evidence

Dawkins imagined memes as self-propagating entities like viruses, but internet culture depended upon active participation. Gladwell’s model of exponential spread fared no better. In practice, most viral content didn’t slowly spread from person to person but relied on “dark broadcasters”—key nodes in the network like 4chan or Boing Boing—that amplified its reach before mainstream media picked it up. The most popular viral music videos, for example, achieved steady growth over time rather than in an explosive curve. — W. David Marx, Blank Space, 188

• XREF: Connects to Milgrom’s work on community reputation nodes and Burroughs’ dark broadcasters idea; also complicates Gladwell’s tipping-point model of exponential spread used in tipping-point literature. — connects to: Early viral-web pioneers formed a scene crossing art, comedy, and network science — Tim Wu, The Attention Merchants, 945; the MOC “The Viral Refinery: How Preexisting Fringe Fears Get Smelted Into Mainstream Reality”
• QUESTION: If virality is hub-driven rather than exponential, what does this imply about how platforms engineer distribution through algorithmic ‘dark broadcasters’ today?
