I'd like to see less about the application of rationality to various different everyday life skills (which usually end up being bad self-help), less navel-gazing about how great we are and how great rationality is, fewer gimmicks, and more attempt to dissolve confusions. explain previously puzzling things, and point out logical pitfalls that one might otherwise fall into. This is what Eliezer did so well in the Sequences, and I can't believe that there aren't any good problems left to cover.
For reference, on the main page right now, here are my classifications:
2 naval gazing 3 reduction attempts 2 self help 2 meetup 1 charity (not sure how to classify)
Are there any areas of study that you feel are underrepresented here, and would be interesting and useful to lesswrongers?
I feel some topics are getting old (Omega, drama about moderation policy, a newcomer telling us our lack of admiration for his ideas is proof of groupthink, Friendly AI, Cryonics, Epistemic vs. Instrumental Rationality, lamenting how we're a bunch of self-centered nerds, etc. ...), and with a bit of luck, we might have some lurkers that are knowledgeable about interesting areas, and didn't think they could contribute.
Please stick to one topic per comment, so that highly-upvoted topics stand out more clearly.
