I agree that a bit of limited moderation would be a good idea, mainly just to consolidate some of the duplicate threads.
I would prefer not to see this forum turned into the heavily moderated AA or UA forums where nearly every thread is merged into megathreads or referred to wikis or stickies, but a little cleaning up would certainly help to improve the usability of the forum. No reason to have two dueling threads on dynamic currency conversion, or the constant Chinese Visa Question threads.
The consolidated threads suggested by moondog are a good start.
