Let's also keep in mind that if true, this is personalization done poorly (for the consumer). Presumably, was no correction in Yahoo's model to consider whether the user liked the content after reading it. The first question here is whether or not the author clicked on more articles leading to more ad views as a result. If so, then it "worked" and made business sense. The second question is whether or not it improved the user's experience, which in this case it obviously did not.
