Please display the number of positive votes and negative votes rather than the difference between them. That way we can see how many people are interested in a feature one way or the other. Displaying only the difference hides that information. I recently upvoted a request for a feature changing the number displayed from -1 to 0. Are there two of us that have voted on that feature or 500? Implement my suggestion and we would know.
