Usually, I receive an email for every comment that goes up on the blog. Today, I have receive zero, which makes it significantly harder to keep up with everything everyone says. (How do you all do it? That Current Comments widget is a life-saver, thank you Chris. Well, and there's the actual feed itself.)
Anyway, I've reported the error to Disqus and in the meantime if someone asks me something directly and I don't answer, there's a very good chance I just didn't see the comment. As always, the Gmail icon in the top left corner is open for anyone to use.
