Google Buzz is a new way to start conversations about the things you find interesting. It’s built right into Gmail, so you don’t have to peck out an entirely new set of friends from scratch — it just works
What Google Buzz Brings?
Buzz brings this network to the surface by automatically setting you up to follow the people you email and chat with the most.
Google Buzz focused on building an easy-to-use sharing experience that richly integrates photos, videos and links, and makes it easy to share publicly or privately (so you don’t have to use different tools to share with different audiences)
Buzz integrates tightly with your existing Gmail inbox, so you’re sure to see the stuff that matters most as it happens in real time.
On your phone, Google Buzz is much more than just a small screen version of the desktop experience.
When it will be rolling out?
It will be rolling out Buzz to all Gmail accounts over the next few days.
Google also plan to make Google Buzz available to businesses and schools using Google Apps, with added features for sharing within organizations.
