StackOverflow is great if your question is "How would we have done X back in 2012?" Because you can't re-ask or re-answer questions that have had their correct answers change as technology changed. So the sites is stuck back in time when each question was first answered.

Sure you can. (But it is a significant problem that they start at the bottom of the score-based answer sort and don’t get attention.)

		This is why you give the updated answer as a comment under the top answer, with a casual "shouldnt we do xyz in [anno domini NOW] instead". Then some established answerer takes what you just said, edits it into the top answer, and steals all credit. But hey, at least you got the answer to be updated, not in your words, and no trace of your input into it. But still updated, right? I'm not pouring one out for SO's death. Because I already did years ago.
