I think it might help the community to stop saying that PubSubHubbub eliminates the need for polling while rssCloud does not.
That just simply isn't true. Polling is what RSS or Atom does when their is neither PSHB or rssCloud. rssCloud merely makes a "request" upon being pinged. No ping, no request. Please don't come back with more about thundering herds. I fully understand both specs. I'm not trying to make a statement about whether one spec is better or not, just addressing the mistaken use of the term polling. I've seen it more than once and it may confuse the less technical people trying to understand these things.
