Did The Verge just post a story or are they asking me a question?
Is Apple testing a new iPhone right now?
Of coarse they are.
Is Eric Schmidt in North Korea to negotiate a hostage release?
I would more information on this! OK, after reading, I see you don't know either.
A good time to use a question mark is if the user won't already know the answer and you have the information you are asking about. It's a sell to get a click. You need a well thought out question and hard information to back the answer inside.
Another possibility... drop the question mark.
