PubSubHubbub allows Design Credo to send realtime notifications when new content is published.
Ever wondered how FriendFeed and GoogleBuzz get updates from your blog so fast and how Netvibes or Google Reader can show you stories that have just been published?
These apps use the PubSubHubbub protocol.
It’s a simple protocol built on HTTP which relies on 3rd parties, called hubs. This page is the hub for Design Credo.
