Bill's absence will be felt for two reasons:
(a) His "hints", even though terse, are enlightening once one gets to understanding them.
(b) More than anyone else, he has been rallying for some social issues as well:
(i) The everyday running of the site should be handled by the community rather than the moderators, to the extent possible.
(ii) Rather than close all questions that are ill-posed, "experts" could use their knowledge and expertise to help the poster arrive at an answerable question.
