For example, what would be inappropriately off topic to post to LessWrong discussion about?
I couldn't find an answer in the FAQ. (Perhaps it'd be worth adding one.) The closest I could find was this:

Well, this discussion would have gone much better if you'd focused on the different definitions of "rational" (and then maybe discuss which is relevant for purposes of evaluating FrameBenignly's suggestions) rather than calling Dahlen "reprehensible" for even bringing the topic of autism up.
I dare say there are many things, in hindsight, that could have led to a more productive discussion. As it happens I'm not convinced you're right in this particular case, but I think arguing the point would be one level of meta too many.
However, it is simply not true that I called Dahlen reprehensible for bringing up the topic of autism. Less importantly, because what I called reprehensible was one of Dahlen's actions, not Dahlen the person. More importantly, because (as I have already said in response to your making the same false accusation elsewhere in ... (read more)
