integrated with GMail

The Buzz API currently provides full support for working with activities, comments, and followers, as described in our Development Guide. We hope to continue improving these APIs as well as to add additional support including federated comments and activities with Salmon, distributed profile and contact information with WebFinger, and much, much more. We invite developers to join us in these conversations on the Buzz API Group. OpenMicroBlogging (OStatus)?
