As such, it retains the right to exist independently of the Stack Overflow company - to my knowledge, it is the only public Stack Exchange site for which this is true.&lt;p&gt;- Like all public Stack Exchange sites, authors retain ownership of their work, which is published under a CC-BY-SA license. Regular archives are uploaded to Archive.org and can be obtained there or via Bittorrent[1]&lt;p&gt;In short, not a walled garden, and not Stack Overflow&amp;#x27;s garden.&lt;p&gt;[0]: &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;meta.mathoverflow.net&amp;#x2F;questions&amp;#x2F;969&amp;#x2F;who-owns-mathoverflow&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;meta.mathoverflow.net&amp;#x2F;questions&amp;#x2F;969&amp;#x2F;who-owns-mathove...&lt;/a&gt;&lt;p&gt;[1]: &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;archive.org&amp;#x2F;details&amp;#x2F;stackexchange&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;archive.org&amp;#x2F;details&amp;#x2F;stackexchange&lt;/a&gt;</text></comment>

With reddit you can end up with a lot of duplicates because a subreddit&amp;#x27;s dashboard decays stuff pretty fast based on the frequency of posts. It makes long-running discussion impossible. With forums you can have your long-running discussions, but you sometimes have to wade through page after page to find those specials nuggets of info.</text></comment>
