The Open Thread posted at the beginning of the month has gotten really, really big, so I've gone ahead and made another one. Post your new discussions here!
This thread is for the discussion of Less Wrong topics that have not appeared in recent posts. If a discussion gets unwieldy, celebrate by turning it into a top-level post.
I comment less now because the combined effect of your & RH's posts made me more eager to listen and less eager to opine. The more I understand the less I think I have much to add.
