I don't see votes as useful signal on Hacker News: for example, during the course of some comments I make, the vote starts out as very negative (from people who skim the comment and think it's insulting) to very positive (from people who read it more carefully and realize it's insightful). So there is a temporal aspect to votes (I'm sure you know more about this than me).A

And often when I get votes, there's no signal whether it's due to tone, or content, or whether it's because I'm expressing something that is true, but makes people feel sad (seems to happen a lot, makes no sense to me).
