He used to be a frequent commenter on Overcoming Bias before Hanson and Yudkowsky split blogs, and he clearly dazzled readers with his refined brand of contrarianism. I wasn’t around to watch, but his comments are occasionally seen under 2007-2008 posts, and later on too. His handle there is/was simply Mencius, search for it.
That matches my (extremely vague) memories much better. I was reading OB back before Yudkowsky created this site. Some of the OB posts and their comments were transferred here, but I didn’t remember Mencius/Yarvin commenting, let alone posting, here too.
It seems like I might have misremembered the details:
Maybe edit the footnote in the post to clarify that Mencius was discussed on and commented at OB before LW ‘split off’?
