From memory there was a time years ago when that's how voting on HN worked, the arrows where just links and returned a 204 no content response. I can't remember exactly but there may not even have been any feedback on the ui (vote count increase or arrows disappearing), although maybe that was done with JS (you could do it with just css now). Have distinct memories of the 204 responses when looking at how HN was made. It's no longer done like that though.
