A modified version of Disqus's universal code for Jekyll posts.

disqus.html

	<div id="disqus_thread"></div>
    <script type="text/javascript">
        /*
		This is the Disqus 'Universal Code' modified to work better with Jekyll.
		You don't need edit here, edit your _config.yml an your post front-matter. 
		*/
        var disqus_shortname = '{{ site.dqshortname }}'; // Set this var in your _config.yml
		/*
		Ideally set disqus_identifier to something unique in the front-matter of each post.
		You need this identifier to be unique and unchanging to maintain the discussion thread for that post.
		By doing this you can ensure that Disqus is unaffected if your post name/date/url gets changed.
		If you don't set it then this will fallback to the automatic page.id var '/2012/12/20/my-post'.
		Page id is better than full url, because its less likely to be changed.

		var disqus_identifier = '{% if page.disqus_identifier %}{{ page.disqus_identifier}}{% else %}{{ page.id }}{% endif %}';
		
		//Below here is identical to what Disqus supply as universal code.
