What is meta? ×
Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 134 Stack Exchange communities.

What should you do if a question has already been asked and answered, but both the question and the answer are now out of date? (in this case due to updates to jQuery).

Is it okay to make a new question if you need an up to date answer?

If you know an up to date answer is it okay to make a new question and answer it? Or should you answer the out of date question?

If you answer the out of date question, wont your answer just be buried and unnoticed because of the already upvoted/selected answers?

EDIT:

The problem is, sometimes a question and its answers will be so hopelessly full of out of date stuff, that it seems crazy to try and put up to date answers on the page. The page is pretty much worthless once the information is out of date, so would it not be better to start a new page?

Short version: edit the answer or question to improve it!

Even anonymous users can suggest edits. Users with 2k+ reputation can edit directly.

Answers:

Edit the existing answer to update it. If you feel an edit is insufficient, or worry that your edit suggestion will not be accepted, write a new answer to the question, then add a comment to the existing answer pointing to your new answer. Indicate in your comment if you feel the answers could possibly be merged.

Questions:

Edit the existing question to update it. If you feel an edit is insufficient, or worry that your edit suggestion will not be accepted, ask your own question, link it to the other question, and explain why you ask again. Flag the question for moderator attention and ask if they can merge the questions.

Fantastic, thanks for the advice! In regards to answering. What should I do if the question has out of date information in it too? Simply comment on it? And when you say "Ask others to merge them", do you mean ask a moderator as with merging questions? And to ask a moderator, should I flag the question for moderator attention? –  Acorn Apr 27 '10 at 10:54
    
@Acorn: out-of-date: If you can't edit, commenting should be suffice. Ask moderator: flag for mod attention. Ask others: Just comment the post and ask: "Could you [which means the post owner here] or someone else please add what I've written here: ..." –  Ladybug Killer Apr 27 '10 at 11:10

Summarise the old Q&A, to make clear why the old answer doesn't help you, and to highlight what new information you are looking for.

Rewritten postscript - As Jeff indicates, you shouldn't worry about your new question being neglected: it is true that new questions don't attract as many views as older answers, but:

  1. Problems with questions stop them from generating better answers;
  2. The new, good answer will be the last thing visitors to the old question see (if they get that far), so misinformation doesn't get corrected; and
  3. the fresher activity on a new question generates interest, especially if you point to your new question in comments on the old page.

The effort of explaining the problem with the old question will probably be worthwhile.

Did you mean to write "answers to old questions being neglected"? Also it wasn't just the fact that they might not be noticed as much, it was also that the question itself contains completely out of date things. –  Acorn Apr 27 '10 at 11:06
    
@Acorn: Three edits each fixed a problem at the expense of unravelling coherence - I've rewritten the postscript now. –  Charles Stewart Jan 9 at 19:16
