HN has been there from the time when I just was dreaming about launching a startup, through the gut check when I finally quit my full-time job to found a startup, selling that startup to another company, being fired by that company, and finally joining a friend's startup as CTO. I've changed throughout, and I've seen Hacker News change as well.
The problem I have witnessed with Hacker News is that over the years, it's transformed from a place where civil and intelligent discourse can be had to a place where each comment seems to be made for show. Rather than making solid arguments, each person seems to want to be seen as more intelligent than the rest of the commenters. This phenomena is the reason for what in my opinion is a breathtaking level of pedantry about the most mundane topics.
For example, there was a post on the front page yesterday about scalability at GitHub. It was an interesting and insightful article from a knowledgeable author. The top comment was something along the lines of, "I can't believe they wasted so much time making the UI look this good." HN used to be a place where insightful articles were rewarded with intelligent conversation and debate. What happened?
Another example. Someone launched a site earlier this week involving the sales of hobbyist electronics. The site was definitely interesting, and they experienced a large volume of traffic from HN and Reddit. The top comment? Something along the lines of, "when a startup can't keep its site up, it makes me question their abilities." HN used to be a site where you would be congratulated for launching. What happened?
It's this kind of stuff that has to go. I don't think Hacker News was ever perfect -- and maybe I'm just rooting for the site because of the potential that it has -- but it's definitely gotten worse over the past few years.
As a community, we need to stop the posturing and the pedantry, and get back to civil and intelligent discourse. We also need to act as the site's immune system, and stop promoting content that is clearly written to be seen but adds nothing to the conversation.
