If there is no category, there are no results submitted to it, so there will not be enough results to be deserving of a category....so the circle goes around and around.
I think I suggested a few years ago that a category should have a certain number of submissions before it is given silverware or points, I still would not mind that happening. (I have a number of 2-point #1 scores, I am not having ideas that do not affect me as well) But... that is an extension of the changes that have just been made, I think the changes are fine for now. Maybe one day, they will need tweaked again, but in my opinion, HWB are on the right path
