I don't know how Hacker News manages to stay so pure, given that it's run by venture capitalists, yet still remains free of ads and open to newcomers. Monetising CS is like demanding a signup fee to join HN: it will drastically change the community.
Hacker News is smaller than most major subreddits in terms of usage. 400 upvotes is considered a lot here. The site is extremely simple and something that could be replicated in a couple of days at most by most engineers. It doesn't process money or really require a lot of content moderation either.
I'm a little skeptical of this. Don't get me wrong, I understand that it's not going to win any ACM awards for innovation in web development - it's a simple web app. I know this. But I think it's well beyond the 2-day prototype mark.
Because I know what a cheapo off-the-shelf, 2-day-product or PHP forum feels like, and Hacker News doesn't feel like that. It's a little more fine-grained and thoughtful than that.
The design, and probably countless little feature improvements that take time to make: I think these have accreted over time, a tiny bit at a time. And for what it's worth, getting comments to nest (stored in DB, parent, child, child of child etc.) and then to show that correctly in the UI isn't quite as easy as people who haven't attempted it might think.
And then things like downvoted comments being faded, next page loading at screen bottom, setting up the API... it all adds up.
