Diaspora is mentioned in the article in the "What about the federated social web?" section. Apparently it is more decentralised than Diaspora. Although I can't see what that means at the moment as implementation details are fairly sparse.

Diaspora and some other platforms are federated communities - in other words, they federate between collections of multiple people. Here, the decentralized social activity occurs between individuals. It's decentralized all the way down.
