Disqus, pronounced "discuss", is an innovative commenting system for bloggers, newspapers, and publishers of web content, etc. It allows you, the reader, to create a free account and be able to track your "comment conversations" across the web in your personal Disqus dashboard.
Lots of folks read and comment on blogs from Blogger, WordPress, Tumblr, etc and each of these sites has their own login system and when you comment there, they are held captive. Imagine all of your comments aggregated in one place. Hello: Disqus.
What pushed me abandon the default Google Blogger commenting system is this little addition: When you connect Twitter to your Disqus account, anytime you leave a comment *anywhere* it can automatically update your Twitter account with a link to the article you just commented on. Check it out here.
As a publisher, this is great news because that means each Disqus commenter's Twitter page will now have the person's comment and a link to the blog post they commented on. The more people who comment, the more exposure my site gets.
For those of you looking to get "quality" updates on your Twitter page, why not create a Disqus account and start by leaving a comment on your favorite blogs?
