Nice bit. But a few observations.
As a former frequenter of SF cons, I can tell you that 1.) not many authors show up at them ... beyond the two or three that they pay to show up for panels and the like. 2.) Most of the convention goers that I know were more interested in the partying than in the Hugo nominations.
I have always thought that the Hugos were more about the sales numbers and the publishers jockeying position. That isn't to say that they are useless or unwarranted. It is more like they don't always get it right <g>
