What is PuSH or PubSubHubbub?

PuSH is a syndication system based on the ATOM format where a publisher tells the world about a Hub that it will notify every time new content is published. Subscribers then tell the Hub “when this Publisher posts new content, please deliver it to me right away.” So instead of the Subscriber checking back with the Publisher all the time to see if there’s new content, they just sit and wait to be told that there is by the Hub. The Publisher publishes something, then tells the Hub that it’s available, then the Hub goes and delivers it to all the Subscribers. This can take as little as a few seconds.
