As far as I know, in order to get RSS in real time (i.e be pubsubhubbub subscriber) , the one who generates the RSS feed, must be a pubsubhubbub publisher, which means the RSS feed must include a tag which includes the HUB address.
However, there are lots of RSS feeds (published using RSS 2.0 only and not pubsubhubbub) which I can subscribe to via Feedly.
How is it possible?
Thanks,
