Btw, I think the simplest solution is to leave the existing market action and general discussion threads as is. But to add another thread as a sticky that is invite-only, determined maybe be a few of the most reputable users. That thread would be high-quality and maybe would allow only 20-30 people to post and everyone to read. But I think the likelihood of this happening is slim to none.
How can we make this happen? Is it just a request to mods/admin? Create a poll?
