I am trying to get a holistic picture of the users' opinions on the site. Both positive and negative reviews are welcome. Being a reasonably broad topic, I will pose some specific questions. Feel free to include in your answers other things that I may fail to mention. Of course you don't have to answer all the questions posed.
Are you happy with the kind of question being posed on the site? Do you find that the site gives satisfactory answers to the questions asked, and has the requisite people to engage you in an interesting discussion.
Is there a well-balanced demographic? Do you find it to be the case that the site targets(perhaps unintentionally) a specific audience, if so which one? If you have been an old user has the demographic of the site shifted in some particular direction.
Are you satisfied with moderation on the site? Have you ever been unfairly treated? Have you noticed instances of other users being unfairly treated?
Are you comfortable with the implementation of network-wide policy? Is there any particular network-wide policy that you wished was different and not applied to Physics Stack Exchange?
Do you find it to be the case that some people whose answers you enjoyed reading have abruptly left the site due to issues that originated within the site? Do you it was due to an issue that can be fixed?
Has anyone's account been suspended unfairly? Or for a much longer duration then you would find reasonable.
Does the site satisfy a researcher's interest, such as finding new topics and problems to learn about? Does it have a sufficient mass of professional physicists?
Please be honest and direct in your reviews.
