Hi all, such a great initiative, really like the concept. I have one question though which I can't seem to find a direct answer to. Does pubsubhubbub hang on the fact that the source website has implemented these push notifications? i.e. pubsubhubbub wouldn't work on an type of rss feed e.g. http://www.artflock.com/artist/lakeillustration/artwork-rss/ ? As per this example artflock.com would have to implement Pubsubhubbub in order to get instant updates?
Thanks :)
