https://newsletter.devmoh.co/p/the-fall-of-stack-overflow-explained Stack Overflow can be a useful resource, but yeah, I would not sign up to it.
I always thought of it as a hostile environment (maybe, not in all the same ways as this article), and for what, some internet points? Better off just figuring out a problem yourself.
I can see why it's going down. If someone doesn't have to ask questions there, why would they?
It's not as if it's pleasant to navigate the pedantic set of rules, the internet points system (which is where you get the middle finger for giving this site free labor), the incorrectly applied rules, or the bizarre decisions of which questions are worthy of allowing someone to answer.
