Looking at Analytics data (the specifics of which as Tim B mentioned cannot be shared in public), I do see a few trends.
We had a huge inflow of new questions right at the beginning of the private beta. That is expected, but depending on how the average is calculated, it also means that any more normal activity level is going to lower the average. The trend for answers is nowhere near as pronounced. On the whole, numbers of both questions and answers are holding relatively steady and have done so for a fair amount of time.
About 10% of our traffic comes from search engines, which I would argue is not bad at all for a site only a month into public beta. Only a few percent is "direct traffic", essentially meaning that someone typed worldbuilding.stackexchange.com into their web browser's address field. The lion's share of the remainder is intra-StackExchange traffic, which likely translates into people being curious about hot network questions.
We are holding steady as far as number of questions being closed, and see a slight uptrend in deleted answers. The former, together with the above, means that question closure is about as common as it has been. The latter is to be expected as the site attracts more traffic.
You have posted at least one question similar to this one before, a week ago now. Personally, I think you worry too much about relatively superficial statistics. Artificially inflating the number of questions won't be of any benefit to the site. Even a relatively low-traffic site can flourish if and only if the content is of high enough quality. If we end up posting questions just to post questions just to boost some average number of questions calculated over some unknown period of time, that is likely to lead to poor quality content which is likely to be a more important factor if the site were to be shut down. The latter which I currently can see no signs of being in the works in any way.
