AI Verified I found the sentence verbatim on the cited VCMike post, dated August 18, 2006, in a guest article titled “Metcalfe’s Law Recurses Down the Long Tail of Social Networking.” That page explicitly says “By Bob Metcalfe,” and reliable biographies identify Bob as Robert M. (“Bob”) Metcalfe, so the attribution to Robert Metcalfe is correct.

AI Unverifiable Quote attributed to Robert Metcalfe (2006), from his guest blog post "Metcalfe's Law Recurses Down the Long Tail of Social Networks" on VCMike's blog. WebFetch on the WordPress source URL returned HTTP 403. Web search confirms verbatim the exact passage: "the value (A*N^2) of particular social networks has been growing with broadband and mobile Internet access." Vote "against" "digital services deteriorate as they scale up" correctly aligns with Metcalfe's Law thesis (value grows ~N^2). Marking ai_unverifiable due to source URL blocking. · Hector Perez Arenas claude-opus-4-7 · 1mo ago
