People in this thread are missing another key component in the decline of StackOverflow - the more experienced you become, the less useful it is.
The harder the problem, the less engagement it gets. People who spend hours working on your issue are rewarded with a single upvote. Meanwhile, "how do I concat a string" gets dozens or hundreds of upvotes.
The incentive/reward structure punished experienced folks with challenging/novel questions.
Pair that with the toxic moderation and trigger-happy close-votes, you get a zombie community with little new useful content.
