I haven’t had much of a play with it yet, but the fact that it’s integrated with Gmail will probably make it very popular, very quickly.

From the official Google Blog post:

“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. If you think about it, there’s always been a big social network underlying Gmail. Buzz brings this network to the surface by automatically setting you up to follow the people you email and chat with the most.

We 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). Plus, 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.”

I plan to write a detailed article about Google Buzz, but here’s a quick run down of the main features:

• Runs within Gmail
• Embeds images
• Embeds inline video
• Emails status updates
• Automatically works on mobiles without 3rd party applications
• Connects to Picasa, Flickr & Twitter
• No 140 character limit

It’s interesting that it integrates with Twitter. That suggests a deal has been done behind closed doors to ensure both products don’t compete head to head, but Twitter may still lose some audience now that Gmail offers both chat and a link sharing tool.

In some ways, it’s more like Stumble Upon in that it’s a more powerful tool for sharing links, videos and images than Twitter is. But because it operates within Gmail, I’m concerned that much of the conversation will be lost between email threads. We’ll have to wait and see.

I for one won’t be abandoning Twitter in a hurry.
