I use Dustsweeper and that upvotes on comments that are less than 0.02. That way if you do upvote, we both get a little dust. I am not asking you to upvote, but I wanted you to be aware that some of the comments will be automatically upvoted by Dustsweeper. And even an upvote that does not generate a monetary reward is appreciated. It shows that someone took the time to read the comment.
