Ask HN: Is 311 Karma Points good?
Really. I don't know. I like the content and occasionally comment. Have not tried to increase it. Should I? How? Why?
HN is a bit better because sometimes you get the rare, unpopular opinion that is well-researched and explained so it makes it to the top.
IMO the best format for discourse is a traditional imageboard/forum where all posts "weigh" the same. It has negatives (nested quotes, thread derailment that you can't hide) but I prefer it to the HN/reddit model.
