<p>I am writing an answer because I do not have enough reputation points to leave a comment. This may not technically be possible, but what if you had the tags themselves guide the direction of the question? For example: someone tags their question as "probability" and "Normal Distribution" on Mathematics (or SO for that matter), and because of the tag, the question jumps over to CV. I understand this is a simplified example and would require a lot of collaboration with Mathematics on who should handle what tags, but it might be worth considering. Also, while I recognize the desire to remain mostly autonomous from Mathematics, it would <strong><em>really</em></strong> be nice to be able to search both CV and Mathematics simultaneously. </p>
