"Google did make announcements though. http://adsenseforfeeds.blogspot.com/2009...... - Google announces PubSubHubBub support in FeedBurner feeds for AdSense, notifying a "Google-run Hub". http://googlereader.blogspot.com/2009...... - Google announces PubSubHubBub support for shared items in Reader. http://buzz.blogger.com/2009...... - "All blog post feeds now contain a "hub" element, and will ping Google's hub on every post update." http://googlecode.blogspot.com/2009...... - "we have gone a step further and added PubSubHubbub support to Google Alerts." I'm not trying to push any blame on Brett. Google owns this now and should help any issues along. I've written about some of the issues I'm seeing with Google's PubSubHubBub Hub. Constructive discussion about the issues I've been seeing is definitely welcome." - Jeremy Felt
