Impressive! 15-minutes after realizing I needed to add comment functionality to some sections of gakushuu.org I had full-featured comments feature seemlessly integrated into the site. Installation was easy, took about 30-seconds from click to test. A rich setup feature allows complete customizing of the comments feature. One of my favorite features is that jcomments is not automatically applied to all articles, but that I can select the specific sections in which I want reader comments. In short, full-featured, seemless integration, easy to install, set-up and use. Another benefit: commercial-grade features at open source cost. Keep up the excellent work. You have my vote.
