Apple and The Masked Blogger

An interesting topic in the blogosphere has been the introduction of The Masked Blogger, an Apple employee speaking about the company on the condition of anonymity. The blogger promises to not speak about SEC-related facts. The blogger instead chooses to talk about every-day topics, giving insight into how Apple works. His contributions have been met with glee and disgust.

How do you feel about this? Should your company have a real, authentic, public blog about what happens in your company? If the answer to that question is no, is it ok for employees to talk about the company anonymously? If the answer to that question is no, is it ok for employees to have blogs talking about the industry they work in, never including anything about the company they work for?
