Is there any work going on to try to put questions in front of people that are the correct expert to answer them?
As an example, when somebody like John Resig logs on, it should be very easy for him to see a few jquery questions that are most in need of his help. Ideally, they would be the most "important" questions, perhaps defined by the the question having more upvotes than any answers. Ideally, should all be inferred automatically without the system having to know that he created jquery, but the idea of people being able to "vote" that a certain user take a look at a question is neat to.
Another variation of this feature is putting answers in front of people that might be able to improve them. Again, if an answer has been accepted but hasn't gotten as many upvotes as the question, perhaps it needs some love from an expert.
