If a story don't appeal to me I see no sense in reading it completely and if I don't read it, I can't give a vote.
But actually you are voting! You are awarding a zero to the stories you don't like. I'm not judging if that's fair or not, but that's what you are doing.
My take is that if you can't commit to read all the stories (and I totally understand that some can't) then pick out as many as you can
in totally random order, read them, and grade them (comments are nice too). If everybody did that, then the averages will prevail, and all stories will get about the same number of readers, and therefore a fair shot.
By the way, I finished grading all the letters today.
