Is there a problem with the hub? I'm not receiving any notifications but if I manually go and publish a topic, the notifications come through.
For example: http://www.nytimes.com/services/xml/rss/nyt/start-ups.xml https://pubsubhubbub.appspot.com/topic-details?hub.url=http%3A%2F%2Fwww.nytimes.com%2Fservices%2Fxml%2Frss%2Fnyt%2Fstart-ups.xml Or http://www.google.com/reader/public/atom/user/18179744707000356486/state/com.google/broadcast https://pubsubhubbub.appspot.com/topic-details?hub.url=http%3A%2F%2Fwww.google.com%2Freader%2Fpublic%2Fatom%2Fuser%2F18179744707000356486%2Fstate%2Fcom.google%2Fbroadcast Thanks!
