I usually upvote what I read, often before reading it because it could pass quite a long time before I can do it. This was a question about upvoting stories, not comments. However many people described how they vote comments, so here's my take on that. I never upvote to agree with something and never downvote to show disagreement. Actually I probably never downvoted anything. I upvote for interesting contributions or to say thanks.
