PG: The biggest source of stress for me at YC was running HN

The key to getting good discussions is to not have a profit motive coupled to eyeballs.

HN doesn't show ads, doesn't care about growth.

Large newspapers had strict firewalls between advertising, journalism and opinion -- but smaller papers had to fold to pressure from advertisers.

Subscription services need eyeballs badly -- but they need paying eyeballs, which means that they need to offer more than just outrage -- but if they don't show at least some of their content for free, they can't grow.

That is plainly insufficient. There's serious outrage, polarization, and lack of nuance on this site about a variety of topics. Privacy, anything google, amazon, or Uber, gender and racial politics, Facebook, etc. There's more going on here than the profit motive.

The problem isn't that these companies want to make a profit. The problem is they make it easy for people to get what they want, and users seek out outrage and polarization. I think that combined with the globalizing tendency of ubiquitous, high bandwidth, low latency, broadcast-capable connections is a real problem. But since I believe it's a human nature thing, I'm much less sure of how to solve it, especially while respecting the free speech value.

Using the fact that CmdrTaco commented in that twitter thread, i want to bring into comment slashdot moderation system. I always thought it was better than simple upvote/downvote because the "tags" (insightful, interesting, flamebait,troll) enticed you to think twice about the modding, preventing knee-jerk nodding reaction.

The fact that often the most voted comments on hacker news are the most extreme (saying something is completely wrong) shows that we love correcting people and will discount a good conversation in place of some virtual approval.

Sometimes I vote something up because I want to see a good counterargument in the replies. Should I not be doing this?

you should vote however you think will foster good discussion, and that sounds like as good a reason as any. another would be voting based on how you think the posts should be ordered from best to worst, regardless of agreement with individual posts.

'voting' doesn't foster good discussion it harms it.
