What is "divulgation"? (Yes, I googled it.) My best guess is that you are not a native speaker of English and this is a poor translation of the cognate you are thinking of.
I assumed it was a neologism for the skill or practice of "divulging things" (which turns out to be pretty close to the author's intent), similar to how we talk of "Bayescraft" or "empirimancy". In any case, it didn't trip up my "non-native speaker" detector ... but then, my threshold's pretty high to begin with.
Basically this: "Eliezer Yudkowsky writes and pretends he's an AI researcher but probably hasn't written so much as an Eliza bot."
While the Eliezer S. Yudkowsky site has lots of divulgation articles and his work on rationality is of indisputable value, I find myself at a loss when I want to respond to this. Which frustrates me very much.
So, to avoid this sort of situation in the future, I have to ask: What did the man, Eliezer S. Yudkowsky, actually accomplish in his own field?
Please don't downvote the hell out of me, I'm just trying to create a future reference for this sort of annoyance.
