If I find similar questions on StackOverflow that haven't been updated in years (which likely include outdated information), is it better to ask a new question, or continue the conversation in the old thread?
Would commenting in the old thread even get any attention?
We don't really have conversations just questions and answers. If the question is still relevant exactly as written you could provide a new answer, if the question itself is out of date then ask a new one and self answer it (assuming you've searched for duplicates first).
You could comment that the answer is out of date but adding a new valid answer would be much more helpful. We don't really want people to read an answer and then read an "only kidding this one's wrong" comment below it. That's a waste of their time.
