It's been an exciting first (partial) week. We've got 105 questions (and counting) with a number of interesting and useful answers. However, I'm concerned that too many of your questions do not, um, play to the strengths of the Stack Exchange network. In particular, more than a few questions so far are probably best answered with an article from some other site on the internet (notably Wikipedia).
Here are a sampling of questions (from different askers) that demonstrate the problem:
One of the things we do to evaluate the health of a site is to grab a sample of questions 10 answered questions from the quarter and ask users to review them. (For an idea of what I mean check out the most recent Academia site eval.) In particular, we are looking to see if our answers are better than what can be found elsewhere on the internet and if they are easy to find via a search engine. Since we are in private beta, Google won't find our answers yet. So I invite you to search for the answers to these questions and consider if the answers we have so far would make you happier than what you find on other sites.
My former colleagues at JPL and NASA are doing some amazing work to educate the public about astronomy. It would make me very sad (and apologetic) if folks can't find that information because this site beats them at SEO. And I'd be doubly put out if our answers were shallow, uninformative and boring. Please ask deeper and more-specific questions. And when you see commonly-asked questions, either write strong answers that improve on easily discovered sources or vote to close (as "too broad", most likely). When we are ready to make the site public, let's make ourselves presentable.
On a related note, I've closed two questions that are more about astronomy as a career field than astronomy itself:
I have mixed feelings about this since there is some merit to having these questions on the site. It's not unnatural that people interested in scientific research would also be interested the scientists who do it. If there were just one such question and if the rest of the site was filled with more meaty questions, I probably wouldn't mention it.
The problem with these questions is that they are really the sort of thing you should ask a career counselor or in chat.
Finally: I've got my eye on you, black-hole tag.
Ask more interesting questions this week than you did last week!
