Google rolled out a social stream service today called Buzz It looks on the surface like Facebook, FriendFeed and other stream reading and writing services. It will compete with Facebook and Twitter. Under the covers, though, this major product was built by a team of people taking a radical new approach to online publishing: Buzz is all about open, standardized user data.
Google Buzz data can be syndicated out to other services using the standard data formats called Atom, Activity Streams, MediaRSS and PubSubHubbub. That couldn’t be more different from Facebook. Google has taken open data standards to battle against a marketplace of competitors that are closed and proprietary to varying degrees. This is a very big deal.
