I'm pretty new to using meta on any of the stackexchange sites. Do the meta sites have the same rigorous standards about what is okay to ask? Is it okay to ask questions that are about something like the nature of the community? To give a concrete example, would something like
Is it my imagination, or are the people on Drupal Answers uniformly more friendly than on other SE sites?
be an acceptable question? If not, why not?
(And yes, I've read the FAQ.)
Acceptable questions on a meta site are also about the community behind the main site too. When you ask if a question is acceptable, and the FAQ doesn't have already specify that kind of question is not acceptable, you are asking to that community if that type of question is acceptable.
That said, the question you used as example is rather subjective. There isn't an objective way to measure the friendliness of a Stack Exchange community, and the question would probably closed as not constructive.
