Diaspora is not about standards. it is about decentralization though. But they want their product to be the one on all the servers.
If you want to look at open standards, look at the stuff around Buzz (not buzz itself) but things like activity streams, Salmon, pubsub. Most of those protocols have been about for ages but are only getting traction now.
The thing that really pisses me off is that instead of talking about protocols, we're talking about diaspora, loading them up with requests and expectations way before there's even a glimmer of a product.
