ETA: There is now a third thread, so send new comments there.
Since the first thread has exceeded 500 comments, it seems time for a new one, with Eliezer's just-posted Chapter 33 & 34 to kick things off.
From previous post:
Spoiler Warning: this thread contains unrot13'd spoilers for Harry Potter and the Methods of Rationality up to the current chapter and for the original Harry Potter series. Please continue to use rot13 for spoilers to other works of fiction, or if you have insider knowledge of future chapters of Harry Potter and the Methods of Rationality.
A suggestion: mention at the top of your comment which chapter you're commenting on, or what chapter you're up to, so that people can understand the context of your comment even after more chapters have been posted. This can also help people avoid reading spoilers for a new chapter before they realize that there is a new chapter.
For a while I've wondered what exactly Robin Hanson is doing (what he's trying to signal, perhaps? I don't know) when he uses abbreviations like "med", "docs", "tech", etc. (Pretty sure there are other common ones not coming to my mind right now.) He doesn't otherwise come off as a lazy writer, he can't really pass for "folksy" (and super-contrarian econblogging isn't quite the right context for that anyway), they aren't difficult or cumbersome words...
It seems to be the titles of his posts and not the content which he likes to keep extremely simple, even trite. I take it as wry counter signalling. There is a touch of ironic contrast between what could superficially look like a naive opinion and reasoning that is in fact based in some measure on sound economic principles, or at least of premises that the intended audience would accept.
