I think the quality of the posts is pretty much the same on all the forum not just the 84 one.
However, this is a very silent and apathetic section. That is the real concern and question. Why is that, given it has the most players, most tribes and a very good amount of "star players"?
What is so fundamentally different on 84 than, let's say, 85, which, by the way has already more posts than the 84 forum. Its the tribe's or player's quality? Is the thin balance, everyone is struggling to keep? Is everyone so strict with their agenda that they fear even to say something that might disturb their plans?
Take a look at the elephant in the room - 420, growing at 5kk ODD in less than a week. No Tyrant, no Why?? has even mentioned that on the forums even if, basically, all the tribes on the whole world noticed it and acknowledged it. There is more talking about that in rank 40+ tribe's Skype rooms than on the W84 chat or on the forums. And if the forums aren't for that kind of subjects, then for what are them?
Cold War time, I suppose.
