My voting behavior on HN is very different from other websites. Since the saved stories and upvotes are the same, and upvotes cannot be taken back, I use the upvote as a "save story" button. There are many submissions which are not of a good quality, but the ensuing discussion on the wider topic prompts me to save the submissions as there is no option to save comments. I maintain a separate database of my saved stories, which I keep preiodically updating and pruning, primarily for NLP and ML experiments. So that is my personally "curated" list of HN bookmarks. Though I must say my visits here have become less frequent.
