In this video interview, Brett Slatkin, Googler and co-creator of PubSubHubbub, talks briefly about his vision of decentralized sharing, where users publish on their own web site and push that content to each other without relying solely on a service like Twitter or Facebook. Looks like he's walking the talk, too. Slatkin appears to publish everything to his own site and re-post it out on social networks (here's his Twitter, Tumblr, and Google+). I'd love to know what his publishing process looks like. The key to popularizing this practice is dead-simple user experience.
