Inspired by this post, I had the idea that browsing questions would be more fun if there was a feature that allowed sorting/filtering/searching based on the number of up-votes a question has received from high karma/reputation users exclusively.
The issue is that a non-trivial number of deep questions are only accessible to an advanced audience, and therefore they don't receive the up-votes and "favorites" that experts might feel they deserve. Don't get me wrong, I think we want to leave question-voting/scoring unchanged. I'm glad newbies can vote. But I think this is an important second-order problem.
We could add this feature without making it super-prominent if we want to keep the UI clean.
This feature would make CV and other SE sites more interesting to experts, and attracting experts has benefits that trickle down to all users.
Thanks to Nick Stauner for suggesting I make this an official feature-request. I encourage all of you to offer more specific suggestions for how it might be implemented.
