See, that's funny, I've been experiencing the "comment drought" for about a week, and only just started *getting* comment emails again yesterday!

I have to say I am highly skeptical of the claim that the problem lies in getting spam-blacklisted. Gmail hasn't been spam-filtering the notices at all, they just stopped showing up. -- Though, hmm, I wonder if I have notifications sent to my brandeis forwarding address, which I *do* think filters at the server level before stuff ever gets to me. I should check that.
