Let's start with a small presentation of the new Google service.

Google finally launched into the world of social networking!

The strong points to remember

• Directly integrated in Gmail, Google's webmail
• A mobile version of Google Buzz with geolocation ...
• An algorithm for ranking and classification of content ... so a priori relevance optimized messages
• Interaction with many services (Flickr, Picasa, Twitter etc ...) but for now Facebook ... Strange is not it? ;-)

It was time to counter Facebook!

Facebook undisputed leader of the social web with over 400 million users worldwide is already well established with a good head start and continuous innovation. But despite Google's delayed reaction can count on Gmail users (180 million) to start the machine.

Nothing is played between two players ... Facebook in turn prepares a webmail to Gmail just to compete ...

So we have to monitor the use and development of Buzz ! But one thing is certain ... In the end, only one remains! :-)
