Good point. Without the name, it's hard to see how it libels (if it's written, it's libel, not slander) the expert. I suppose it might be considered defamatory

Good point. Without the name, it's hard to see how it libels (if it's written, it's libel, not slander) the expert. I suppose it might be considered defamatory if there were only one math education expert at Stanford and everyone knew who that was, but that seems implausible.
