It's very different these days. I've said similar things a number of times.
~15 years ago HN was full of really interesting deep dives into technical topics. There used to be articles about different algorithms, frameworks, programming languages, etc. Back then I even used to write tech posts and tutorials myself and share them here with some success.
The other thing I miss are the entrepreneurial posts... My friend introduced me to HN because I was interested in business and tech, but I didn't really get the appeal of HN for a while. But I remember when I was like 19, browsing HN during my lunch break at my crappy retail job and found this,
