Perhaps relevant to this thread: I wrote up a sequence on decision analysis which parellels the semester-long graduate course on decision analysis I took fairly closely.
I do think reading the sequences is a decent at creating an intellectual foundation that works, which is what most students probably want out of an introduction to philosophy class, but most introduction to philosophy classes train students to recognize historical philosophical positions, which reading the sequences does not do.
I'm finding it difficult to compare LW to math/physics/compsci classes I've taken, with the exception of probability classes, where I think I've gotten more from working through the math than discussing Bayesianism. I think I've enjoyed time on LW more than any of the 'soft' classes I've taken, with perhaps one exception (a class entitled Alternatives to Violence taught by Colman McCarthy).
I imagine that reading LW might represent more knowledge than a business degree, but by "reading LW" I mean both reading LW and reading LW recommended books, like The Personal MBA (whose author posts here) and recommendations from this thread. (Implicit here is that part of reading LW and being active on LW is following the trails you find on LW; I think much of the value that gwern adds to LW is done on his personal site, and Yvain posts mostly offsite these days, and so on. LW seems good at sorting information, which is a rather valuable service.)
Compared to many of the people reading this, I've not participated extensively on LessWrong. In fact, I created my account only about a week ago. That said, I have read many LessWrong articles by contributors such as Eliezer, Jonah, Yvain, Gwern, and many others (if I missed you, my apologies). I wouldn't say it was a huge transformative experience. But I have probably learned a bit more from LessWrong than I learned sitting in on a class by Nobel Prize-winning economist Gary Becker on human capital (without formally registering for the class or doing the coursework). I've learned more of value from LessWrong than all the MIT OpenCourseWare lectures I've consumed. There are a few online experiences, such as reading EconLog, that have been more educational for me than LessWrong, but I can count these on the fingers of one hand.
Some of my friends have claimed that reading LessWrong systematically (and perhaps participating in the comments and attempting to write posts) would generate more value for an undergraduate than a typical core college class (with the possible exception of technical classes specific to the person's major or area of specialization). I'm curious about whether readers agree with this assessment. Do you feel, for instance, that LessWrong provided you with more valuable human capital than your introductory general chemistry sequence? What about comparing LessWrong with an undergraduate "intro to philosophy" class? Or an undergraduate intro class on the history of economic thought? At what percentile would you rank LessWrong relative to your college classes?
A second related question is whether there's a possibility of building a college course -- or college-like course, perhaps a MOOC -- specifically revolving around mastery of the content in LessWrong (perhaps starting with the Sequences). Would such a college course be possible to design in principle? How would such a college course compare with core requirements for undergraduates today?
