I learn about new and old things that people share. I generally dislike when I see the same things for months/years (self-driving stuff, cryptocurrencies, AI).

I learn about new and old things that people share. I generally dislike when I see the same things for months/years (self-driving stuff, cryptocurrencies, AI). But in general, I feel like I learn a lot of stuff from HN. Sometimes, the comments direct me to Wikipedia and I end up learning even more about some old thing that solves everyday coding problems.
