I just realized I was missing about a week’s worth of comments from this blog. It looks like Google Reader at some point stopped tracking the comments (which is how I knew you were commenting), and I missed a few great ones, including one from BJ Fogg, whom I look up to. My apologies if it has taken awhile for me to respond to your comments.
If you want to track any of the comments feeds for any particular article, simply view the article, and append, “/feed” to the end and add it to your favorite RSS Reader. It will then send you updates of all comments for that article. Or, you can just click the checkbox next to, “Notify me of followup comments via e-mail” below the Captcha and it will e-mail you updates.
My apologies if I have not responded very quickly lately – that should be fixed now.
