Support for real-time feeds has so far been much stronger on the publisher side than the consumer technology side. With blog publishing services WordPress, Blogger and Typepad all adding Pubsubhubbub or RSSCloud feeds to their offerings, there are now hundreds of millions of real-time feeds available in those two formats. So far only a few small feed readers have begun consuming these feeds; RSSCloud developer Dave Winer's own River2 , a complex but customizable desktop feed reader, and LazyFeed , a simple but enjoyable feed-powered discovery engine, have turned on full support for real-time feeds. Real time didn't come up in interviews this week with the creators of NetNewsWire and FeedDemon . Google Reader implemented very limited support for PubSubHubbub in August, just pushing a Hubbub feed of "shared items" from Reader to the now-Facebook owned FriendFeed . In that case Google Reader was playing the part of the publisher and FriendFeed was the reader.
XMPP
Microsoft has announced that it is adding support for XMPP to its Windows Live APIs, enabling any application or IM network to interoperate with Windows Live Messenger. Details are available at liveside.net and dev.live.com. September 14, 2011
What is it ?
Slatkin starts out by explaining the value propositions of real-time data delivery, with an emphasis on social networking because he's speaking at Facebook. He then goes on to discuss how PubSubHubbub works and how to implement it. He also spends several slides discussing what he considers the technical shortcomings of other real-time protocols, particularly RSSCloud , but that's only a small part of the talk. Slatkin will be participating in the Real-Time Web Summit next month.

For more information on PubSubHubbub check out a great post by Dave Winer, the father of RSS. Friendfeed is already benefiting from the PubSubHubbub experience. If you're currently sharing Reader items in your Friendfeed account, your Friendfeed subscribers can already see your updates in real time.

The Future
Jive points to a number of examples. Tivo, they say, no longer requires your box to check in with the Tivo servers periodically - the server sends a signal via XMPP to available boxes when new information is published. Tivo is essentially using machine-to-machine Instant Messaging for real time communication within its service. Dave Winer says XMPP could be the foundation of a decentralized version of Twitter . Valley golden-boy startup Seesmic is using XMPP for messaging and AOL has reportedly begun experimenting with it as well. The Google-acquired Jaiku microblogging platform used XMPP heavily.
