Right now I am erring on the side of caution; I'd rather write something obvious to everyone than skip an inferential distance somewhere.
That seems like the best policy to me, especially for a site like LW. Perhaps on OB that could be a concern, but here where it's so easy to avoid the posts you don't want to read or which aren't upvoted much, having redundant information doesn't seem like it would be too much of a problem.
One of the missions of OB/LW is to attract new learners, and it's clear that they are succeeding. But the format feels like a very difficult one for those new to these ideas, with beginner-level ideas interspersed with advanced or unsettled theory and meta-level discussions. You wouldn't play <insert cool-sounding, anime-ish video game here> with the levels on shuffle mode, but reading Less Wrong must feel like doing so for initiates.
How do we make the site better for learners? Provide a "syllabus" that shows a series of OB and LW posts which should be read in order? Have a separate beginner site or feed or header? Put labels on posts that designate them with a level?
