This Saturday, the Castilleja School, an all-girls' college-prep academy in Palo Alto, has invited Hewlett-Packard CEO Mark Hurd, Google fashionista Marissa Mayer, and Wikipedia founder Jimmy Wales to a symposium on leadership. What, exactly, does Wales propose to teach, I wonder?

How to have a failed career as an options trader? How to build a porn site? How to launch, inadvertently, the world's seventh most popular website and yet avoid making any money on it? How to hire a convicted felon as chief operating officer of a nonprofit? How not to build a Google-killing search engine? How to cheat on one's spouse, get a divorce, and neglect one's seven-year-old daughter? These topics would be fit additions to the sum of all human knowledge, and yet I doubt Wales will address them.
