First off, there's way too many threads in the forum with absolutely no discussion value at all to the majority of the TW players as well as a severe lack of intellectual debates - especially in the forums designated for each world.
IF you create them, they will come.. Many of the more intellectual posters lurk the forums, looking for something to post towards, something to debate. Many do it through Skype, and real time chats, and in tribal forums.. But if you start the threads, with a well thought out idea, or thread, you will draw that creative conversation you crave, and can enjoy it again.
I feel your pain though, 90% of what I read is utter garbage. Just need to learn to block it out, and enjoy the 10%.
Moreover, where are the moderators? Some threads are merely spam and nothing else.
We are here, but for the most part we also adapt to our environment. If we lock down every thread that comes out, you'll hear crickets. We have to find a balance between what's breaking the rules vs. entertainment value. Unfortunately a thread where people are showing support to the poster, isn't something that breaks the rules, and while I might consider it spam because I don't enjoy the mindless content, there are people who feel that's them giving an opinion.
I'm sure if you took it up with your forum mod, and asked to be allowed to create a thread or two for serious discussion, they'd keep the thread clean to your liking, I know I'd enjoy doing that, just to be able to see some real discussion again.
Next, newbies are in many instances frowned upon and ridiculed. Obviously this is not needed to be explained further.
This is an issue with society more so than the TW forums, and it's sad truly. The modern day hero is something of an anomally. I heard a story the other day, of someone passing out in a medical studies class. They called emergency services, and everyone sat there and just looked on, waited for an ambulance to arrive. Did anyone try to resuscitate? Sad really when you think of it, they were there training to be doctors.
If someone with this 'elitist' status were to stand up for the newbs in their forums, you'd find the forums a very different place. But people are afraid of being flamed, so they sit back and watch others get fried. It at least gives me a little hope that people see the problems out there, the next step is to act on fixing them.
