Thanks Brett. That seems to make sense but I am still facing a problem. Currently I am subscribed to http://realtime-web.blogspot.com/feeds/posts/default
Now I dont even get a notification from http://pubsubhubbub.appspot.com/publish. My subscribe request still returned me a "No Content". When I look at the publisher diagnostics, I see the following error message: "Could not find any record for topic URL: http://realtime-web.blogspot.com/feeds/posts/default"; Could it be that this is getting canonicalized to the older URL and so not creating a topic for the new one?
