Comments update: they're working on it

In my last post I mentioned that I was no longer receiving email notifications of comments submitted to this blog. I thought I had fixed the problem, but no. Even the dozens of comments that I posted three days ago (after finding them languishing in my "awaiting moderation" folder) have disappeared. I now discover that the same problem has been experienced by other bloggers. Google says it's aware of the problem and is working on a fix.  Sigh.
