Is it true that Hacker News is based on a game theory... where users play a game to get points... and this game keeps HN alive? same goes for Reddit.
What views you have ?
The community keeps HN alive not the point system. I don't really get why there is a point system in the first place... It's not because someone is considered as a troll on some subjects that when he post on a topic he know and is right that is post should automatically lower on the page.
