What if I see a question that I know the answer to, but it has already been correctly answered? Should I give my own answer if I feel that my answer is better than the one that has already been provided?
We have a policy of deleting duplicate answers. That only applies to answers that don't add anything on the existing answers, though. If you believe you can provide a better answer, feel free! If you can provide a better answer, you have nothing to worry about.
A better answer doesn't necessarily add anything, and if you're not adding anything you can probably just edit the existing one– AequitasDec 3, 2015 at 2:08
9@Aequitas A better answer doesn't automatically have to add something new; we'd prefer it, yes, but if its a better quality answer, we'd be doing ourselves a disservice by deleting it. That's meant more for those one liners we often get, where new users think we're a forum and chime in with their two cents. Editing shouldn't be the default action; people can, and should, provide their own answers, if its higher quality. They're putting in the effort; its only fair they get the reward.– FrankDec 3, 2015 at 2:14
4The way I see it, "better quality" has value in and of itself and a high quality answer added to lower-quality answers therefore does add something, namely quality.– MrLemonDec 3, 2015 at 12:46
What is the approved method of dealing with such answers? Flagging? If so, what flag? I get so many of these declined– kalinaDec 4, 2015 at 15:17
@Kalina Duplicate answers? Downvote. At 20k, vote to delete the answer. The Low Quality queue takes care of the rest.– FrankDec 4, 2015 at 15:45
so no flags? sadface– kalinaDec 4, 2015 at 15:47
If you can improve the existing answer by editing, without changing their intent, then do so. So, you could improve formatting, spelling, grammar, phrasing, add a screenshot, that sort of thing.
Here's an example of a question that already had an upvoted accepted answer that I thought had a problem. I started to edit it, then realized I would be changing the actual content, and instead posted a new answer.
Kalina has since edited the answer to account for the problem I noticed, but you can see the previous version in the edit history.
If you think you have a better answer than the best answered answer, you could try I believe. Even if you do not have a better answer, you may still help them out with your answer! Everyone likes to help others.
No. Posting duplicate answers doesn't help anyone and adds more work to the review queue. Dec 4, 2015 at 8:21
