(I&#x27;m not an admin. You probably want to email HN because they won&#x27;t see the question otherwise.)<p>In the past HN had a fairly strict dupe-detection filter.<p>That meant that a lot of good stories that didn&#x27;t get attention on the first posting didn&#x27;t get reposted.<p>Currently the dupe-detection is much weaker than it used to be. A story that didn&#x27;t get much attention on the first post can be reposted easily now.<p>HN tried an experiment where they&#x27;d email people and ask them to repost submissions, and give those reposts a small bump.  That was a lot of work, so they only do that for &quot;Show HNs&quot;.  Now they do something like an auto-repost which resets the timestamp.<p>This means that sometimes you&#x27;ll post something, and it won&#x27;t get much attention, and a few hours later someone else will post the same thing and it&#x27;ll get upvotes.<p>This isn&#x27;t going to stay like it is. They&#x27;re working on a better system.<p><a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=10754760" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=10754760</a><p>&gt;&gt; We&#x27;ve recently started doing things to make the original submitter get the front-page slot more often<p><a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=10753401" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=10753401</a><p>&gt;&gt; Invited reposts are mostly deprecated now in favor of re-ups [1], but when it looks like the submitter might also be the author (as e.g. with Show HNs), we still send them. It&#x27;s nice for an author to know that their post may still get discussed, and it&#x27;s good for HN when an author jumps into the thread.<p><a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=10705926" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=10705926</a><p>(A meta post, with links to previous discussion).
