I agree it was a moderation issue, but for me it's Reddit that largely replaced my SO usage starting some years ago. Reddit is pretty similar to SO in design, but the more decentralized nature of the moderation means that questions rarely get "closed as duplicate" and answers tend to be more up-to-date as a result. There's not always a consensus answer and I'm often looking across multiple threads on the same thing, but that's still better than an outdated SO post.
