IMO the outdated info problem is the biggest one Stack Overflow has right now, much worse than posts getting flagged as dupes on a questionable basis. Theoretically, you're just supposed to add a new answer that's better — but you almost certainly won't get the checkmark, and you probably won't even get more votes than the old answer (since your answer will only get search traffic and not front-page traffic, and you're already below all the other answers to begin with). So Stack Overflow slowly transforms into w3schools.
