It seems to me that we're out of moderators on SuperUser. Diago's off for the next 2 weeks (seeing how much he works to keep SU running properly, he deserves it), and all the other moderators have had limited interaction lately with SU. Looking at their profiles, they've mostly stopped answering any questions by September 14.
I'm worried that this might become a problem; in my opinion, moderators have a very important role in the well functioning of these sites.
