<p>The question is pretty much answered in the comments (and complemented in the brief exchange in chat), but I'll compile all that here just to make sure the question isn't left unanswered.</p>

<p>Basically, we're not the best place for open-ended discussions. As <a href="https://stats.stackexchange.com/tour">the tour</a> points out, our model is best suited to "[a]sk questions, get answers, no distractions" and that you shouldn't ask "[q]uestions with too many possible answers or that would require an extremely long answer."</p>

<p>Simply put, we're not a forum. Still, <a href="https://stats.stackexchange.com/tour">as Scortchi points out in a comment above</a>:</p>

<blockquote>
  <p>pertinent addenda, amplifications, caveats, corrections, criticisms, &amp;c. arising from discussion in comments are eventually digested &amp; assimilated into well-crafted answers</p>
</blockquote>

<p>That leads us to comments, then: the tour page also adds that "This site is all about <strong>getting answers</strong>. It's not a discussion forum. There's no chit-chat." </p>

<p>The different communities in the network all use the same model, but have slight differences on how they handle discussion in the comment sections, and when to clean these up — but as the above quote says, the approach that best suits our model is to avoid extended discussion in comments, and these are considered ephemeral and disposable.</p>

<p>That being said, <a href="https://stats.meta.stackexchange.com/questions/4891/creation-of-topics-instead-of-questions-for-linking-with-course-notes#comment13967_4891">as Scortchi points out in the same comment above</a>, that doesn't mean the communities are fanatic (or sometime they're just not always extremely diligent) in enforcing these policies; especially if the discussion in question is actually a good and productive one.</p>

<p>All that being said, if you can find a way to frame your posts as actual questions that need actual answers, as opposed to posts that simply invite open-ended discussions, I believe this is a good place for you to do so. If the open-endedness is something you're striving for, though, maybe we're not the best place — <a href="https://www.discourse.org/" rel="nofollow noreferrer">Discourse</a> might be a good alternative :)</p>

<p>With regards to how to tag these, should you come to the conclusion that you can find a way to make the discussions/questions fit in well with our model, I'll defer to you and the community — the community is really better suited to figure out how to categorize their content than I am. </p>
