> Every entrepreneur is now a psychologist by trade. The ONLY thing that matters to success in our anything-is-buildable Internet world is psychology. How does the customer perceive this product? What causes someone to share? What makes virality happen? What makes something sticky?

That sounds like marketing, not psychology. Of course, marketing is heavily relying on psychology, but still.

Marketing is psychology, for all intents and purposes. Nothing is purchased without a decision at some point filtering through a human brain. Marketing is simply the business/economic side of psychology.
