Speaking only for myself. I have never nominated for Hugos and only voted once that only for the Campbell for a friend. I never nominate because I rarely read a book, story, or see the movie the year it is eligible; I am anywhere from one to two years behind in reading to over a decade behind. Same goes for voting not having read the nominees it would be random dart throw picks not what anyone wants to see. I could catch up after the nominees are announced if I wanted to and had the time but honestly most of it is not to my taste.

My Two Cents,YMMV
