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.
Now this is pretty meaningless, but in many words purporting to explain something. Beware curiosity-stoppers.
Edit: I misinterpreted mwaser's comment, correction.
It is a definition, not an explanation. I misunderstood his post to be questioning what the quoted word "structures" meant so I provided a definition.
I am editing it to provide examples. It was certainly not intended as a curiosity-stopper.
As a definition, it had meaning -- but none that was new to you.
