Ok, so I think I’ve figured out what was going on. During the upgrade to the latest and greatest WordPress my FeedBurner re-route plugin stopped working, and FeedBurner lost contact with my blog. You may not have seen a difference in the RSS feed, depending upon how you subscribed, but email updates stopped because as far as FeedBurner was concerned the blog hadn’t been updated and so no email was needed.
I think that’s all fixed now, but I won’t know for sure until between 1 and 3 pm central time tomorrow when we see if the email update goes out. Wonder if it will be two weeks long?
