Learn cool technology, build cool things, meet cool people.
Now, HN is one of the more pessimistic communities I frequent. Most posts are berating or belittling the author, the technology, someone's politics, other commenters, capitalism in general, and so on. It's all so tiresome to read and the amount of time and energy wasted doesn't hold a candle to whatever the AI companies are doing. It's gotten to the point that I pretty much never scroll past halfway down the comments page, because that is almost always about where the useless and most whiney comments tend to start. It used to be lower, like 10-20%. It may be creeping up even higher.
I would love to find an online community where the pessimists don't rule the roost. Haven't found it yet, but if anyone wants to drop me a hint, my contact info is in my profile.
