When the OP asks a question, the title box contains the hint
what's your language learning question?
so the OP duly types in his question:
What's the difference between these two sentences?
This as an appropriate response to the hint, but it's about as much use as [substitute your favourite metaphor here].
Would it be worth while changing the hint to say something like
What's your question about?
or something suggesting (as briefly as possible) that the title should help people with the same question to find it.
So, two questions: should it be changed, and if so, what should the new hint be?
