Ohhhhh. WOW! Damn. Now I feel bad.
I have been acting like a bull in a china shop, been an extremely ungracious guest, and have taken longer than I prefer to realize these things.
My deepest apologies.
My only defenses or mitigating circumstances:
1. I really didn't get it
2. My intentions were good
I would like to perform a penance of creating or helping to create a newbie's guide to LessWrong. Doing so will clarify and consolidate my understanding and hopefully provide a useful community resource in recompense for the above and appreciation for those who took the time to write thoughtful comments. Obviously, though, doing so will require more patience and help from the community (particularly since I am certainly aware that I have no idea how to calibrate how much, if anything, you actually want to make too easily accessible) -- so this is a also request for that patience and help (and I'm making the assumption that the request will be answered by the replies ;-).
Thanks.
Ditto. I think the more general rule is that you're expected to have read the common background on a topic you're posting about. It's okay not to know anything about quantum mechanics as long as you don't go posting about how everyone else has got it all wrong.
I think that's less due to a community-accepted rule and more because you can't get called out on not having the background reading if you don't demonstrate that you lack it.
It's still a good guideline for newbies to adhere to, though.
