Typically questions should be phrased as a question with the who, what, where, when, why, and how. However this isn't your typical question as it garnered a high amount of traffic, and votes. Also, and more importantly, the title did state the original intent of the OP. IMO, as long as the title gives a semblance of the problem at hand it's ok. For example take a look at this title:
Transatlantic ping faster than sending a pixel to the screen?
Yes it does have a question mark, but in reality it's not a question. Where's the who, what, where, when, why and how of this question? If we were to hold the same standards here, the question should be rephrased as:
Why is a transatlantic ping faster than sending a pixel to a screen?
Taking on a question mark doesn't make the post an actual question. We could do the same for this post:
Blank Screen If Kids Yell Too Much?
But it's still not a question per se. However, from both titles you can get the basic idea of what the OP is having a problem with, or the end goal they are seeking.
I'm not saying that your edit was wrong, nor was @Oliver's actions, I'm just trying to present a case where the OP may have felt that it was ok.
