Using "What" in the title was a mistake here. When you see "What" you expect mostly facts, mostly findings. If they had titled it with "How" I would have been more prepared for a lack of immediate answer. "How" denotes that an explanation is needed, and backstory is often necessary in explaining.

Titles are especially important on the web because links only have titles. There's no other context to which you can get an idea of what you're getting into. It's not like in newspapers where you have the context of what section an article is in or visually see how long it is from a glance.
