I'm going to guess that you got downvoted as people felt your comment didn't add anything to the discussion, which is the prescribed use for downvotes. The article already explained the rational for adding it and that it wasn't actually used. It's likely clear to you why your response was also downvoted.
I got downvoted -12 a few weeks ago for saying that an article mentioning John Regehr was the professor from the University of Utah that I respected. What the fuck is that? This website is overrun with nerds with small egos.
You said "I saw Regehr and knew it had to be the U prof."
How did you expect people to respond to that comment? The comment adds nothing to understanding of the article. The comment adds nothing to understanding of the author of the article.
