I have also added the ability to use trackback.
This is for all of you bloggers out there who would like to comment on my post from within the comfort and convenience of your own blog or web site. Simply write a new post on your blog or web site, link to my post, and use the trackback link to ping my blog. This will update my trackback list with a link to your blog so that interested readers can follow the discussion from my site to yours. It's a great way to help us both build traffic and is perfect for those of you who don't want to be limited to the confines of my comment environment.
