I don't think the idea itself is so terrible - there are a lot of social networks that largely duplicate each others' functionality, and it would be great if newcomers to the field could link in to a meta-network so that they were actually useful without building up huge userbases first. Facebook would have a lot less lock-in if I was able to build my own social service with some set of better features and people could choose to use it instead of Facebook, yet still reach everyone they used to interact with on Facebook without them all switching, too. But... OK, so my Facebook status, Twitter tweets, and Livejournal musings are all on this fancy standard ...and this might help somebody, somewhere, if any of those services were actually on this fancy standard. I don't see any evidence that they are - I only see "Google Buzz, StatusNet, WordPress.com, and Tumblr have implemented some or all of these protocols today", which is a long shot from any true unification. Or am I missing some other large set of supported sites?
