Google May 19 launched its promised Google Buzz API at Google I/O, and a number of applications are already integrating with the service, including social app Seesmic and Boxee. How do these apps integrate with Buzz? Seesmic and Buzz users can now manage Buzz in their browser through Seesmic Web, through a beta version of Seesmic for Android and in Seesmic's preview version of the new Seesmic Desktop.
