Following on the heels of today's announcement on Buzz, we're excited to bring you the latest on all things social at Google I/O, starting with a session on Buzz APIs and a new panel session!

What's the hubbub about Google Buzz APIs?
Google Buzz is a new way to share updates, photos, videos and more, and start conversations about the things you find interesting. In this session, we'll take a deep dive into building with the Buzz APIs and the open standards it uses, such as ActivityStrea.ms, PubSubHubbub, OAuth, Salmon and WebFinger.

Where is the social web going next?
With the advent of social protocols like OAuth, OpenID and ActivityStrea.ms, it's clear that the web has gone social and is becoming more open. Adam Nash (LinkedIn), Daniel Raffel (Yahoo), John Panzer (Google), Lili Cheng (Microsoft), Monica Keller (MySpace), and Ryan Sarver (Twitter) will discuss the importance of such emerging technologies, how they've adopted them in their products and debate what's next.

Here are additional sessions that'll give you a deep dive into the emerging technologies and standards that will help you create a more engaging user experience for your web applications and sites, and enable a people-centric web.You'll also have the opportunity to meet developers from the following companies in the Social Web pod of the Developer Sandbox: Atlassian, eBay, IBM, LinkedIn, MySpace, Ning, Playfish, Yahoo!, and Voxeo. They'll be demoing their social apps, talking in-depth about integrating with various Google technologies, answering questions, and chatting with attendees.
