Edit: After discussion I realize that in my answer here I was really thinking more about the future state of the site, rather than the specific requirements of private beta. I no longer hold this opinion precisely.
One reason to have some of these more general questions is to provide potential canonical answers to future questions from many newcomers. Another reason is it provides a base of general knowledge over time. Anyone who has spent time on sister sites like Stack Overflow can see how over time, questions become more and more specific as the general cases gain answers that are widely accepted by the community.
That's not to say we shouldn't have very specific questions: ask away! Rather, in my opinion it's very helpful, especially at first,
to "seed" the site with some as long as they are solid, commonly-asked questions, both to provide examples of strong questions and answers and to provide someplace for newcomers to start.
Note that I'm not talking about questions that are too generic or opinion-based and thus off-topic, e.g. "Is beer good for you?" or "What is the best kind of beer?", or filling the site with junk questions just to make it appear active.
Unless the audience of the site is "only experts may apply", which I didn't think it was, there is nothing wrong with a well-written, direct, non-expert question.
