I was just looking at FrostFyre's comment against this question and it occurred to me that it's already articulated in a manner in which I would've written it.
I don't see any reason why the title shouldn't articulate the question itself, and you then use the body of the post to set your scene, show your research to date and provide sufficient boundary to the scope.
Is there a specific reason that we should ask posters to reiterate their question in the body if the title is an adequate formulation of it?
I'm of the view that the answer should be no, but I'm happy to be proven wrong if there's a good reason for the contrary position. The only possible reason I can think of (not being a mobile consumer of SE) is that the title may not be as prominent in certain smaller interfaces, like mobile.
