Things are pretty settled now on serving; if you have any issues with your FeedBlitz feed, please check / update its settings, and then email support if there’s a problem you can’t resolve.
The circulation counts of zero do NOT mean you’ve lost your subscribers! They’re still getting the updates.
What it means is simply this: The RSS service’s log analysis and reporting engine hasn’t been started yet, since we’ve been focusing on getting your word out to your readers first.
We’ll be moving on to restarting the analytics tomorrow, but meanwhile, don’t freak out ! If you can see your feed, so you can your readers. There’s nothing for you to do about this – it’s entirely our issue to resolve here.
So to recap: Subscribers are getting the updates, FeedBlitz just has’t gotten around to updating the circulations yet.
