As I've stated in the past, I'd strongly support it. I've participated on another board that went from being unmoderated to being moderated by volunteers and things got much better after the change.

The advantages I saw were:

- Less and shorter flame wars, as they got headed off at the pass.

- Fewer personal attacks.

I didn't see a single disadvantage. The moderators were well chosen, and there was rarely controversy about what they said.
