Is this exchange for only technical questions? Or is there a place for higher level curiosity questions?
According to http://area51.stackexchange.com/proposals/43283/space-exploration the questions per day is low, although there are a great number of users. Could the technical barrier to asking a good question be factoring into the low number of questions asked?
As a new user to this exchange, I asked What is the smallest starting object that could reach Mars? I quickly responded to helpful comments asking that I narrow down the question. Afterwards the question attracted a couple of really good answers.
