The RES (Reddit Enhancement Suite) browser extension indirectly does this for me since it tracks the lifetime number of upvotes I give other users. So when I stumble upon a thread with a user with like +40 I know "This is someone whom I've repeatedly found to have good takes" (depending on the context).
It's subjective of course but at least it's transparently so.
I just think it's neat that it's kinda sorta a loose proxy for what you're talking about but done in arguably the simplest way possible.
That assumes your upvotes in the past were a good proxy for being correct today. You could have both been wrong.
I am not a Redditor, but RES sounds like it would increase the ‘echo-chamber’ effect, rather than improving one’s understanding of contributors’ calibration.
