Well not entrepreneurship as such, but more like discussions about entrepreneurship. There's all sorts of things in the process that could benefit from rationality, and it'd be nice to see them expanded on: How to pick an idea, How to build a team, Whether starting a business is a good use of time to begin with, etc.
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.
