It’s not that the WordPress comment system has anything entirely lacking for a basic site, but that the DISQUS comment system adds much more.
It’s a community across the web, with real-time discussion, social sharing (and tagging) with single sign-on, and easy moderation. Remember those spam comments/notifications from the default WordPress system? Yup, that’s why we went looking.
