I would have to agree with Motnot. I think the "general" forums require the least moderation, as their generality allows for more freedom.

Moderators (IMHO) are needed much more in the airline and hotel specific forums, where many a fight has errupted over the last year, and off-topic and inappropriate comments really detract from the directions of the forum.

We've seen ethnicities questioned, airlines policies misstated, people challenged and harassed for posting legitmate opinions, hundreds of frivolous, misplaced posts and outright flame wars. For the many that have reduced theit Flyertalk time to just the "meat" of the issues, the specific forums are the ones needing a level head to keep them on track.
