Migration to JS-Kit comments had numerous additional positive side effects (the first one was that the commenting system finally started to work, resulting in a significant increase in the number of comments). Among other goodies, JS-Kit supports Facebook Connect: you can post comments on my blog using your Facebook account (the initial setup could fail occasionally, but it looks more like a Facebook failure). The comments made from a Facebook account are automatically inserted in your Facebook newsfeed (if you so desire).
