I realize that some people like them; I do NOT. Still, they are popular and one has to learn to live with them. But this author has totally exaggerated. It was difficult to even read the article; I'm not sure I was even able to grasp the content of the article, and have no intention of going back to try to "read" it again,with all those ugly yellow faces ,some of them jumping about...no, no, no. Horrible.
