Disqus and Drupal

Disqus a commenting service that allows users to sign in using multiple-platforms. The service provides every moderation setting you could possibly need conveniently located on Disqus.com in an administration area. Disqus supports integration with Facebook, Twitter, and other social networks. The immediate benefits of Disqus of Drupal's core comment module are as follows:

• The initial CSS theming looks better to that of Drupal's system comment.css styles.
• Drupal can be themed easily because the elements are not loaded via an Iframe but use Javascript.
• Disqus 2.0 allows users to backup comment posts on their own database, this means that search engine optimization (SEO) is not affected negatively by loading comments in from another source.
• Disqus works with views in most cases.

A negative feature of the Disqus commenting module may be in some advanced sorting or Views setups that may not be able to manipulate outsourced comments as effectively as comments hosted on a Drupal database. The biggest problem with Disqus rests in advanced Drupal setups that have large amounts of users already registered via a Drupal mechanism and need comments to be correlated with those users. These setups however often miss out if they are not connecting with Facebook. I wonder if there is a way to combine all three functionalities?
