you probably don’t even need explicit voting. Google already tries to figure out which results a person found useful just based on existing UI interactions, and use that in the rankings. if they operated a significant social media arm, they could link these two datasets to basically the same effect we’re all speaking of here.
heck they maybe already do this in a different/more hierarchical form based on a person’s Youtube graph.

They don't seem to be using that data to improve search results. I've noticed a considerable decline over the years, and Google is now definitely my 2nd or 3rd choice when I'm trying to find something.
