Questions are like buses: nothing for a while, then they all come along at once.
There are lots of unanswered questions out there, and many of them are easy, some don’t make sense, and a few have meat on the bone. I try to find the latter within my scope.
And I do have to sleep now and then! I often leave unanswered questions for many hours thinking that some user may choose to answer it. But quite often, nobody bothers.
