It’s made Dave Winer happy, which is no easy task, so I think PubSubHubbub is worth mentioning here. If it’s working as it should, this post should appear in my Google Reader, almost immediately after I’ve published it. That’s because PubSubHubbub is “a simple, open, server-to-server web-hook-based pubsub (publish/subscribe) protocol as an extension to Atom [and RSS].” My blog feed is managed by FeedBurner which has already implemented the new protocol, as has Google Reader FriendFeed. They should therefore ‘talk’ to each other in realtime. Watch the video and you’ll see how it works. It’s pretty straightforward. It just takes a company the size of Google to push it through to adoption. The engineers say they were using it like Instant Messaging the night before the demo, which says something about how responsive this is. Technically, it should be another challenge to Twitter in that it allows for a distributed method of near realtime communication. I’d like to see that. I feel like an idiot communicating within the confines of Twitter, sometimes.
