Stack Overflow hasn’t been useful for at least 10 years, if not longer.

The flagged “correct” answer is almost always wrong due to idiotic power-users and the vast horde of idiots who upvote obviously wrong answers because they’re bootlickers. The real answer is usually buried in between the posts by gatekeepers, pedants, idiots with something to prove, wannabe admins, egotistical idiots, the highly opinionated technologically insecure, etc ad nauseam. Reddit is just as bad for tech questions, if not worse.

Since I started using LLMs (running on my own inference server) I haven’t used anything else for tech questions that wasn’t opinion-based. Much, much more useful, and it requires you to think seriously about the problem to come up with a good prompt – which often gives you the answer before you even finish the prompt.
