I consume the RSS firehose exclusively, so I guess the answer is "constantly". I have no idea which submissions are highly voted.
To be clear, I'm not reading tons of submissions. I just don't like the idea of only being presented with the top N submissions by vote count. I'd rather scroll a feed that auto-marks each one as read until I see something interesting.
I have the same problem with YouTube. I (almost) only consume entire channels via RSS feeds (sans shorts). I never see the home page, and I only occasionally click an algorithmic recommendation.
