Interesting, but I don&#x27;t think it&#x27;s useful because it doesn&#x27;t actually tell you if previous discussion exists or not until you actually click it.  I&#x27;m not going to click &quot;past&quot; on every story for the 1% chance that it will actually have results.<p>For it to be useful (to me at least), it should only show up if previous discussion exists, and it should be more prominent.
