<p><strong>Strongly related</strong>: <a href="https://meta.stackexchange.com/questions/9050/how-do-we-deal-with-octuplicate-questions">How do we deal with octuplicate questions?</a></p> <p>This is not a question about how to deal with duplicates, it's a simple "meta" question: </p> <p>What is the most rampant duplicate on Stack Overflow? </p> <ul> <li>The particular duplicate must be "alive" on Stack Overflow (not merged or closed duplicate) </li> <li>The duplicate-ness must be pretty unquestionable. </li> </ul> <p>For example: </p> <p>This is a duplicate of score <s>2</s> 1. </p> <ul> <li><s><a href="https://stackoverflow.com/questions/227662/what-is-the-best-editor-or-ide-for-ruby-development">https://stackoverflow.com/questions/227662/what-is-the-best-editor-or-ide-for-ruby-development</a></s> merged ;-p</li> <li><a href="https://stackoverflow.com/questions/59968/best-editor-for-ruby">https://stackoverflow.com/questions/59968/best-editor-for-ruby</a></li> </ul> <p>They are both so close that it makes little sense to have separate questions. </p> <p>However, score 2 is pretty uninteresting. </p> <p>(The rationale of this question is to find the duplicates so we can get the administrators to merge them. It is also to find better ways to find dupes in the first place, and perhaps turn finding duplicates into a game.) </p>

<p>This is quite "rampant": <a href="https://stackoverflow.com/questions/1082555/best-java-7-features">Best Java 7 features</a></p> <p>Pretty much exact duplicate of <a href="https://stackoverflow.com/questions/214289/what-new-features-in-java-7-do-you-find-most-useful">What new features in java 7 do you find most useful?</a> (posted 9 months earlier), very close to <a href="https://stackoverflow.com/questions/460938/what-are-you-looking-forward-to-in-java-7">What are you looking forward to in Java 7?</a> (6 months earlier), and somewhat close to <a href="https://stackoverflow.com/questions/tagged/java7">many others</a>.</p> <p>What also springs to mind are the <em>countless</em> variations on the theme "What is the best Python (web) framework?", with ever so subtle differences in emphasis and formulation. (Right now I'm not delving too deep into those, but take a look at <a href="https://stackoverflow.com/questions/tagged/python+frameworks">python+frameworks</a>, <a href="https://stackoverflow.com/questions/tagged/python+framework">python+framework</a> and <a href="https://stackoverflow.com/questions/tagged/web-frameworks+python">python+web-frameworks</a>.)</p>

<p>Having voted to close more than 1600 questions, and succeeding in many of them, these are the two I found (anecdotal) most annoying (in number, yes) from C#/.NET world:</p> <ol> <li><p><a href="https://stackoverflow.com/questions/273941/get-property-name-and-type-using-lambda-expression">Get property name and type using lambda expression</a></p></li> <li><p>And even more duplicated is this: <a href="https://stackoverflow.com/questions/75746/conditional-operator-assignment-with-nullablevalue-types">Conditional operator assignment with Nullable&lt;value&gt; types?</a></p></li> <li><p>And even more: <a href="https://stackoverflow.com/questions/266115/pass-an-instantiated-system-type-as-a-type-parameter-for-a-generic-class?lq=1">Pass An Instantiated System.Type as a Type Parameter for a Generic Class</a></p></li> </ol> <p>That's just from my experience. The language designers can take a cue to find the most requested feature..</p>

<p><strong>Data query tested in 2016</strong></p> <p>Shog9's Data Explorer query didn't seem to work for me, so I crafted one that did: <a href="https://data.stackexchange.com/stackoverflow/query/254033/rampant-duplicates-questions-with-the-most-duplicates" rel="nofollow noreferrer">https://data.stackexchange.com/stackoverflow/query/254033/rampant-duplicates-questions-with-the-most-duplicates</a></p> <pre><code>SELECT TOP 100 l.RelatedPostId AS [Post Link], COUNT(l.PostId) AS DupCount FROM PostLinks l WHERE l.LinkTypeId = 3 GROUP BY l.RelatedPostId ORDER BY DupCount DESC </code></pre>
