The rise and rise of the ?

Online newspapers just love posting articles with titles that have question marks. This is why:

1. They can post the cheap brain farts of pseudo experts and keep some (very vague) semblance of authoritativeness, and

2. Readers that disagree with the proposition don’t switch off until after they click through and read a few paragraphs, and

3. Readers that are enticed by the proposition click through, and

4. In both cases 2 and 3 advertising revenues are earned. This is gaming of the advertising metrics related to their revenues

And it’s implied question marks as well as literal ones.

As in (thanks SMH) “Mother explores cause for child’s uneven teeth. You will be shocked at what happened next.”

What?
