It seems volunteer moderation may not scale well at a company this size.

When I consider that the logs of these intranet conversations are a legal liability, and moderation actions may cause legal challenges as well, it strikes me that perhaps google should hire professional moderators that report up through their legal division.

I imagine a lot of employees might balk at this, but having developers losing sleep over how to respond to intranet drama may be considered undesirable as well.
