It may be, as has been stated in previous posts/threads, the staff/mods are extremely busy with outside lives and this is a part time gig. And asking what appears to be a simple question, and having to provide a fair and balanced response, might require a fair amount of investigation.
Combine part time job, with a laundry list of other site related activity, along with some lead time to research answers I could see where potentially a response could take a while on a site that has this many members and activity.
The staff can comment on how the list of question sent via the contact form is attacked in terms of priority. First in, first out? Easy question in, easy answer out are processed first? Hard question in, hard answer out, processed last? I don't know...
