I downvote poorly thought comments, although given some of the abusive uses of downvoting here, I would rather that it not exist. I upvote articles I find to be interesting reads, articles worth significant discussion on subject matter (tech or non-tech related - does not even have to be math/science/engineering related), or comments to counter bad downvoting. I also will upvote comments I like due to thoroughness, even if I disagree with the argument(s) made.
