Easy. I want a headline that accurately reflects the content of the article. That is my, and perhaps a few others, personal definition of a "good" headline.

Easy. I want a headline that accurately reflects the content of the article. That is my, and perhaps a few others, personal definition of a "good" headline. That is not being measured. Given that definition, I may not go read the article because it doesn't interest me. It is still a good headline. I didn't waste my time. On the other hand, if I am interested in the content, I would have read the article and would not be irritated that I had been mislead about the content. The metric being used in the article here in no way leads to this definition of a "good" headline. More likely the opposite.
