<p>One thing I could think of is to add a "relevant questions" list below or side the main question. This will let users and musing curators know that the question was already asked before.</p><p>They could further improve this one to, letting musing curators or moderators hide repeated questions visually or through UI.</p>

<p>I don’t see this as a major problem. Yes, musers should do their part and search for similar questions before asking. But some questions do deserve a second asking, especially when there aren’t enough or satisfactory answers given before. </p><p>I used Quora a lot and had seen repetitive questions being asked. However, as the topic interests me, I don’t mind reading new answers to it. You will always find better answers given in a different perspective. I find that beneficial for the platform. </p><p>Instead, I would suggest musers not to post too many questions a day, in the hope of earning upvotes. Some questions that I came across are really unworthy for this platform. A simple 1 minute search on google is enough to get the answer, but yet they prefer to ask it here. What a waste of our time and resource. </p>

<p>Probably nothing, apart improve the categories and the search experience</p>

<p>Preventing people from asking a question that has already been asked is pretty difficult actually. The best option I can think of right now would be to incentivize people to post something like "This question has already been answered at URL", and then have a moderator merge the two questions. Or something like that. I cannot think of a solution that would not require a lot of manual labor from either the users or the moderators.&nbsp;</p>
