Should we be trying to spread the word?
No. The people who value 'intrinsic rationality', who accept the various premises and ideas that are prerequisites for liking LW/OB stuff - they are mostly being reached already. It may not look like it, but there aren't a whole lot of them.
Vastly many more people value utilitarian rationality, but LW/OB stuff doesn't seem to help very much in that respect, and the good things we do have like the near/far view are either unconvincingly new, or taken from elsewhere. If we were to push LW/OB to such people, they would reject it as being useless, conclude it is a failed program, and never ever come near it again. (This is akin to software releases; you don't want to push a buggy release as 1.0, because people will never ever forget.)
