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.
Seconded.
Actually, more than this, if we have members who think they've got a good approach to investment, either their own or a published one they'd endorse, I'd love to see a public longitudinal "bake-off" of those approaches. That is, start with $N and see what each approach nets given real-world events over X months.
Similarly, let people go public with their predictions and confidence levels thereof.
Actually give us a chance to see how various approaches work.
