This suggestion runs very close to the edge of what SO is for. Although it does conform quite nicely to the way SO is used. :)
StackOverflow is meant as a Q & A site. More than that, it is meant to be a specific and technical Q & A site. This means that the perfect question (assuming it is well written) would be some sort of bug or obscure framework error. Other options would be a question about how to work around a specific technical limitation.
The major theme of all of them is that the user is approaching a concrete problem, with actionable solutions. That way if other users are experiencing the same scenario they can enact the same resolution with hopefully the same result.
Upvotes are garnered by solutions which (theoretically) all solve the problem, with the "best" or most elegant solution bubbling to the top. This means that every StackOverflow problem should be relatively irrelevant to anyone who doesn't have that problem.
That is to say, every post should be tailored to it's context. Generalized to help the maximum amount of people with that problem.
This makes "Recommended Question" a little out-of-scope. For a question to be applicable enough to be "Everyone should read this!" it has to be far too general to be actionably solvable. How can one question be specifically solvable in all OS' and all languages? Well, it would have to be an algorithm question, but each algorithm is designed to solve a particular problem, which means that the "Recommended Question" would only be applicable to people who already have that problem, in which case they would be better served by just searching for it.
This means that "Recommended Question" would end up being used for the generalized or subjective questions, which are discouraged anyway.
Lastly, as squillman notes, the "Recommended Questions" could just be considered the questions which are highest voted.
