In graph theory, a network is nodes (the people) joined by
edges (relationships that actually carry weight). Its strength isn't the
node count — it's whether the edges hold when you pull on them.
That's why this doesn't use an average. It uses the geometric mean, where
one weak dimension drags the whole result down — exactly the way a single missing
edge can disconnect an otherwise dense graph. Score 10 on peers and 10 on experts but 1 on
isolation and you get 40, not 70. Because a brilliant network you never
call isn't a network. It's a contact list.
Mastering the quality of your network means raising the weakest edge,
not collecting more nodes.
