--- WHY CHOOSE DISQUS? HIGHLIGHTS OF THE DISQUS COMMENT SYSTEM ---
Web comments can be difficult for both websites and their readers. We think Disqus is the solution. Disqus makes it easier for people to comment and track their contributions on a single profile which they can display as a comment blog. After all, there is no difference between a great comment and a great published article.
Disqus makes managing discussions on one or multiple websites painless. With a powerful and intuitive admin interface, Disqus allows website owners to spend time elsewhere while Disqus takes care of the comments.

The only comment to do about it is that, despite the developer has a plugin for their big component K2 in their website, that plugin is not compatible with Joomla 1.7 yet, what is really a pity.
