There has been a lot of discussions about the level of the questions and the quality of the questions.
It seems to me that we have a core group of users, that are following Physics SE from a long time, and that this group would prefer to have a Physics SE closer to mathoverflow than to Math SE as it is now.
We also have this new proposal for a theoretical physics SE.
My questions is: what should we do now ? Could we try to move the center of mass of this site more on the "research level" side ? How could we do it ?
Should we close more questions ?
We already have quite a high number of questions, so slowing things down (by closing question) is not a problem I think. In addition we still have time to modify the way things are going, we are still a the begining of the beta.
Another action would be to change the definition of the site to clearly reflect the expected level: is it possible ?
I don't think we should give up now and consider the site "dead".
What's your opinion about that ?
Edit
It appears that "research level" is a bit too restrictive: as pointed by @Noldorin, questions related to (under)grad course are interesting as well, my idea is that such an undergrad student would not ask "What is the most efficient way to destroy the universe?" ...
Questions that are not research level but coming from an (under)grad course can really benefit from answers coming from real physics practitioner.
My conclusion: in any way the level, at this moment, is too low and we should try to restrict the range of questions, and maybe even more importantly up vote good answers (which is easier to do if the questions are more interesting).
