I noticed that too, but I started getting them again yesterday (mind you, I was getting the diegest version - I'm not sure how people are going that get the immediate version?).
I think the emails from the bloke on vacation were just a glitch with an auto reply setting.
I started getting them again yesterday as well, both the digest and immediate. I didn't get any emails from the guy on vacation this time, but I have in the past.
