Conjecture

The internet both fragments and concentrates attention, because networks carry positive feedback: information cascades, where people treat other people's choices as evidence of quality under high search and opportunity costs, and reputational cascades, where people conform to signal belonging.

Weakest point: the mechanisms are plausible and the distributions are observed, but the link between them is inferred rather than demonstrated.
