I feel that a lot of what's in LW (written by Eliezer or others) should be in mainstream academia. Not necessarily the most controversial views (the insistence on the MW hypothesis, cryonics, the FAI ...), but a lot of the work on overcoming biases should be there, be criticized there and be improved there.
For example, a few debiasing methods and a more formal explanation of LW's peculiar solution to free will (and more, these are only examples).
I don't really get why LW's content isn't in mainstream academia to be honest.
I get that peer review is not the best (far from it, although it's still the best we have, and post-publication peer-review is also improving, see PubPeer), that some would too readily dismiss LW's content, but not all. Lots would play by the rules and provide genuine criticisms during peer-review (which will lead to the alteration of the content of course), along with criticisms post publication. This is in my opinion something that has to happen.
LW, Eliezer, etc, can't stay on the "crank" level, not playing by the rules, publishing books and no papers. Blogs are indeed faster and reach a bigger amount of people, but I'm not arguing for only publishing in academia. Blogs can (and should) continue.
Tell me what you think, as I seem to have missed something with this topic.
Same reason why milesmathis (google it, have fun) isn't taken, and shouldn't be taken seriously by the mainstream. Because "playing by the rules" didn't work - you usually end up with an unending amount of crackpottery in what is actually not published: books, blogs, etc.
Not publishing in the mainstream while publishing books and self published articles is the crackpott's artillery, unfortunately.
Think like the mainstream: given the amount of crazy stuff that's present on the internet that couldn't be published because it was, indeed, crazy, should I care about this particular guy that doesn't publish anything but books (or self published articles) ? The unfortunate answer is no.
