Found this on Leo Laporte's site. It's a threaded commenting system from http://www.disqus.com/
What's really nice is you can sign up and any time you comment on a site using this tool your comments are aggregated for you into your own personal page. It's a threaded commenting system so you can see all the replies to your comments.
Of course I had to give it a try. They did a great job showing you step by step how to install it on your blogging platform. In fact they even modified the XML template for you.
Give it a try... leave a comment. I don't get many :-(
