Hi there, I'm not sure is this a solution but it's works fine for me. 1.) Use http://ninuatest.blogspot.com/feeds/posts/default instead of http://www.blogger.com/feeds/6999034805426555507/posts/default 2.) After subscribe your blog at pubsubhubbub.appspot.com, go to https://pubsubhubbub.appspot.com/publish and publish http://ninuatest.blogspot.com/feeds/posts/default manually. You will receive a notification with few feeds inside.
Hope this method works fine for you too.
