What is Google Buzz ?

So what exactly is Google Buzz? Used on a PC or mobile, Buzz reminds us of an RSS combined with all of your social networking—all within the existing Gmail and Google.com infrastructure.

Buzz’s five key features include:
• Automatic friends lists (friends are added automatically who you have emailed on Gmail)
• “Rich fast sharing” combines sources like Picasa and Twitter into a single feed, and it includes full-sized photo browsing
• Public and private sharing (swap between family and friends)
• Inbox integration (instead of emailing you with updates, like Facebook might, Buzz features emails that update dynamically with all Buzz thread content, like the photo viewer we mentioned above)
• “Recommended Buzz” puts friend-of-friend content into your stream, even if you’re not acquainted. Recommendations learn over time with your feedback.

Google Buzz is available today, and it should creep up as a new tab in Gmail any minute.

The Buzz listing looks more like Facebook than it does Twitter, with Likes, dislikes and the ability to respond directly to a posting and have other people see it. When someone makes a new comment in reply to an old Buzz, it bumps that entire Buzz up to the top.

What’s weird, and what Matt and I can’t figure out yet, is how some people are able to find us on Buzz. Is it searching by real name? It’s also interesting that this is tied to your Gmail account. When people do a search for you, it doesn’t seem like it exposes your actual email address, which is a good privacy protection wall.
