What sets ArtofComments apart is the tight integration with Joomla forms. Comments are enabled within the edit form for an article or category - no need to remember dozens of category or article id's.
* Enable or disable comments for any category - right in the edit form.
* Enable or disable comments for single articles - right in the article edit form.
* Support Disqus developer mode to test comments on local testing sites.
If i had to make one recommendation it would be to add a comment counter into the category blog view so you can see the number of comments before reading the full article.
I would definitely recommend this plugin to anyone looking to implement Discuss into their Joomla site.
