It seems it would be very useful to see a summary of metrics such as question closure rates, perhaps broken down by moderator and reason, so the community can get a sense of the current trends and perhaps identify improvement pathways. As one frequently hears something along the lines of: in order to fix something, you need to measure it first.
Having these metrics publicly visible would be a great feature to the platform. Perhaps these are already readily available in the "back-end," created by the data-scientists/analysts that work for Stack Exchange.
Thank you.
