Just for reference (I did not know about it)

Betteridge's Law: "Any headline which ends in a question mark can be answered by the word no." [1]

[1] http://en.wikipedia.org/wiki/Betteridge's_law_of_headlines

"Betteridge's observation of some headlines that end in question marks"

This "law" fails many tabloid-style headlines, and other obvious cases.

eg.

"Where's the money?" (headline about corruption involving tax-payer money)

"Is Betteridge's Law of headlines ever worth invoking?"

"Manchester United: Will they ever return to form?"

Betteridge's Law of Headlines should really be referenced more often with clickbaity titles like this.

I wish either the title requirements or HN users with sufficient karma could allow/add a @SavedYouAClick-style tag to these stories that would list on the front page ("Will the Ebola Virus Go Airborne? [Probably Not]"), rather than having the Betteridge's Law of Headlines discussion in every such thread.

Agreed, that would be even better still.

Someone was collecting all the times it got references on HN. It was useful the first few times, after that it became a race to see who could post "FRIST", er, "BETTERIDGE" in each comment section.
