I'd like to see more rationality materials for people of average intelligence

Actually, search for "Center for Modern Rationality" and a post along the lines of "Name new Rationality Inst." - the latter describes an organization Eliezer is making as a spinoff and explains that it's going to have materials for high school students. They ARE trying to branch out to the rest of the population! This is exciting! (: I wonder how far they've gotten.

As for your other suggestions, I've begun talking about that again in my preventing endless September thread. You're invited to check out the cliff notes version and request new pros and cons be added.
