"In the networked web era, influentials may not be people with a particularly connected temperament or Rolodex, or people who control and influence monopoly distribution channels (e.g. newspapers), but rather people who influence the network by leveraging the most powerful force on the web — the link.

"Journalists and PR professionals, the influence brokers of traditional media, have lost a huge degree of influence on the web in large part because they don’t link to anything.
