When Jakob Nielsen shares good advice with us: Mastery, Mystery, and Misery: The Ideologies of Web Design:
Designs that support user empowerment are the best way to make money on the Internet. It's an easier sell when you give people what they want than when you try to cheat them.
I would just add that it's not necessarily about making money on the internet, this advice applies to any kind of site, even corporate sites.
And that mastery wins in the end can only please your padawan webmaster ;-).
