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:
What is Less Wrong?
Less Wrong is an online community for discussion of rationality. Topics of interest include decision theory, philosophy, self-improvement, cognitive science, psychology, artificial intelligence, game theory, metamathematics, logic, evolutionary psychology, economics, and the far future.
However "rationality" can be interpreted broadly enough that rational discussion of anything would count, and my experience reading LW is compatible with this interpretation being applied by posters. Indeed my experience seems to suggest that practically everything is on topic; political discussion of certain sorts is frowned upon, but not due to being off topic. People often post about things far removed from the topics of interest. And some of these topics are very broad: it seems that a lot of material about self-improvement is acceptable, for instance.
I would strongly disagree with that statement; both in your depiction of LessWrong and your depiction of autistics. I think if you made a list of all the things other communities avoid; many of theirs would be much, much longer. I would say it would contain many of the same items on the above list. I myself find graphic depictions of violence very disturbing. It deeply troubles me that so many people enjoy watching it. I'm not sure what limits this places on my rationality. I can still discuss violence in the abstract, but avoid discussing it in the concrete. But most internet communities would frown upon graphic depictions of violence too. LessWrong tends to have a lot of abstract discussions and only a few concrete discussions. This is typical of many internet forum discussions; not just exclusive to LessWrong. My guess is this is a much greater cause of bias than limits on what type of concrete discussions can come up.
I would be less opposed to graphic depictions of sex, but I would certainly never begin including it on here because I know many would find it offensive. I also believe it would lead to a deterioration of the quality of forum posts. I am not sure what limits this places on others' rationality either; this strikes me as more of a personal choice.
As I said, I'm least certain about how pop culture and art discussions would be received. My guess is this would be okay if it differed from the sort of content which can be easily located elsewhere on the internet. I'm guessing I would get quickly downvoted if I posted a review of the latest Star Wars trailer, but might do okay with a discussion of calculations of the cost of the Death Star, which got brought up on Marginal Revolution once, but I'm too lazy to look it up. There's also a selection effect in that LessWrong is mostly computational and natural science types with very few people from a humanities background. This is probably a huge source of group think bias, but it would be difficult to surmise what effects this bias has. As for humor, many LW users seem to have a poorly calibrated sarcasm detector. A recent example; before I replied, fubarobfusco was at -2 for that comment.
I'm not sure I would describe fubarobfusco's comment as sarcastic, and I am not at all convinced that the reason why it was at -2 for a while was that early readers didn't understand that fubarobfusco wasn't literally claiming that typical modern office environments involve being "crammed up against other people with nothing to do" like cattle on a farm. I think it's more likely just that a couple of the first people to see the comment happened not to ... (read more)
