Google Mobile Blog
Google today announced Buzz, a social network tool integrated with Gmail that is part Twitter, part Foursquare and part FriendFeed. For mobile users, the service is available as a Google "web app" on any GPS-enabled smart phone and as a standalone application on Android phones. Either version enables users to "check in" and associate their status updates or shared items with a specific location. : "Your location brings valuable context to the information you share. For example, does 'Delicious dinner!' mean you're at a great restaurant, or that you had a wonderful home-cooked meal? Your mobile phone, which is with you almost all the time, can help answer these questions."
