I really find it discouraging that Sam Altman is at the top of that list. Most of his articles fall into two categories: promoting things that will make him money directly[1], or myopic musings/self-serving advice to people that will make him money indirectly[2].

Is the HN algorithm rigged in favour of things he writes, or does this community really get a lot out the things he says?
