Commenting and Trackback added

In an effort to continue improving this site, I have added what I believe is a simpler commenting interface, as well as the ability to Trackback my posts. I have linked to many others bloggers, and I would like to support them. Trackbacks will make this much easier to do. I have also heard that it has been somewhat annoying to login each time a comment is entered, and I have hopefully alleviated that problem. Please let me know your thoughts or issues.
