I wouldn't call Can the Chain Still Hold You? a "Yay rationality" post; more just generally inspirational. But yeah, I'm with you.

Fittingly, this website provides several examples of how even when talking about rationality, we (humans) still have a tendency to lapse. One of the most annoying: most of the metaethics sequence seems to be designed to make the reader feel good about Yudkowsky's metaethical position, rather than argue for it and/or explain it.
