Thom, my guess is that Eliezer thought this post was sufficiently Hanson-esque to appeal to readers of OB that haven’t been following Less Wrong. Characteristics of Hanson-esque blog posts: frequent external references, short, frequent questions to readers. I suspect this post wouldn’t be voted up much on Less Wrong, so perhaps the OB/LW split makes some amount of sense.
