Yes. I've been a semi-regular reader of OCB for about a year. I think it's an interesting blog. But have I learned anything useful from it? Has it made any practical difference in the choices I make, either day-to-day or longterm? The answer is no. Admittedly, this may be my own fault. But I recall a post, not too long ago, soliciting people's feedback on "the most important thing you learned from OCB in the past year," or something of that sort. And while there were lots of people excitedly posting about how much OCB has taught them, the examples they gave were along the lines of "I learned the power of fundamental attribution error!" or "I learned the importance of continually adjusting my priors!" with curiously few examples of real differences OCB made in anyone's practical choices. This raises the question: if tweaking our rationality has no appreciable affect on anything, then how can we say we're really tweaking our rationality at all? Perhaps we're just swapping new explanations for fundamentally irrational processes that are far too buried and obscure to be accessible to us.

That said, I think things like the recent posts on akrasia are strong moves in the right direction. Intellectually interesting, but with easy to grasp real-world implications.
