Well, I'm one of those people who doesn't like to nominate if I haven't read at least the majority of the eligible stories. The subset of stories I do read is relatively random, but it may be skewed toward certain authors, certain genres, whether or not I have time to read it when the story first comes out, etc. So it doesn't seem fair to nominate those stories over other stories that might be equally good but for whatever reason I haven't read yet.
On the other hand, I don't wish to presume to tell other people how to nominate <g>. So I voted Other on the second question.
