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.
That could be useful (R is open source too, and seems to be more popular than Octave or even Matlab).
What would also be useful would be tips on how to present data in a understandable, attractive, and non-misleading way (i.e. not a bunch of tables or a basic unreadable scatterplot).
I'm thinking of Razib Khan's posts, who tend to have nice eye-candy. Developping those kind of skills in LessWrongers would be neat.
