Steve Jobs isn't on Facebook. Now his wife has disappeared from the site. A few days ago, we posted about Laurene Powell-Jobs's Facebook page, and her curious membership in the Apple network, normally restricted to employees. Today, it has disappeared from view entirely. It's not visible to anyone searching for her name or from within the Apple network, to which she belongs.

Two likely scenarios: One, she cranked up Facebook CEO Mark Zuckerberg's vaunted privacy controls, making her profile visible only to designated friends. Two, she used Facebook's new account-deletion tools to leave the site altogether.

However, this doesn't change our initial concern. Why does Powell-Jobs have an email address if she doesn't work at the company? We confirmed her Apple email address through outside sources. We would contact Apple PR about it, but what are the odds we would get a response?
