This is probably a duplicate of "Is this site only for "expert-level questions"?" but somehow I wasn't able to see from the question (and its answers) what we do with very simple questions, now that we are in the public beta.
"what is the optimum level of production?" is the perfect example for that - it is really basic (imho not even an Econ 101 question). However, I don't know if I should vote to close the question or not. The OP has clearly tried to answer the question by himself and knows that something is wrong. So the only reason I see for closing this question is: It is too basic.
