At the moment I don't think we have good answers for the core questions. Good reasoning is hard. Pretending that it's possible by following a few quick fixes might make it easier to reach more people but it brings in people who don't belong.
I take it the point is to bring in people who don't belong yet but who might turn out to belong when they've thought about it some more.
(Not necessarily to Less Wrong as such -- which might do best to remain a forum for sometimes-intimidatingly-technical discussion that preferentially attracts the very clever -- but to "the broader rationalist community".)
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
