Comments can be threaded so you guys can carry on your own mini conversations about topics within the comment section. You guys will also receive email alerts if someone directly replies to your comment. If you're on twitter, you can also choose an option to simultaneously send a tweet when you comment on a post.
The main difference for you guys is you will have to change your login a bit. You can either sign in as a guest, create an intense debate profile, or use your Open ID account. If you already use Google or Blogger, you have an Open ID account. Click here for info on how to use it.
With all changes on my site, I welcome feedback. Love it? Hate it? Let me know! Also, this is the first post with the new comment feature, so help me test it out, k?
