For myself, this is part of why I am disinclined to nominate people who have already received the award in that category. I believe there is a lot of excellence in sf, and even if someone continues to be a favorite of mine, I'd like more people to get the same well-deserved recognition. Every time someone nominates a person who is frequently nominated and well-known, that raises the bar for others who are up and coming but possibly just as excellent.
This year, I noticed that my strong desire to see particular nominees on the ballot in same cases led me to put fewer than 5 nominees in a category, especially ones that are historically under-nominated and the numbers are therefore closer together. Correspondingly, I find there are rarely nominees on the ballot in those categories I'm disappointed with.
In well-nominated categories like best short story, on the other hand, I make sure to nominate a full slate, as there are so many excellent options, yet every year I see one or two nominees make the ballot that are disappointing if not outright embarassing.
