Proposed Q&A site for astronomers and astrophysicists.
Sorry, I can't commit because I'm not an expert and only 'just curious'.
Shouldn't the description be changed to something to include 'anyone interested' or so?
No, that would not be a good idea. The purpose of the proposal is to attract a group of expert to create an interesting canon of reliable knowledge within the field of astronomy.
Certainly you are welcome to participate — we're not exactly checking credentials at the door — but in terms of giving of beginners top-billing as the intended audience for this site, we are designing a site for experts. To attract experts, you need a site where colleagues are asking very interesting and challenging questions.
Remember that an expert site will attract the enthusiasts, but that does not work the other way around. A site full of beginning users will not sustain the site in the longer term, and many proposals (and a few early sites) have failed from being filled with the merely curious.
