Google Public Location Badge
Google have released a Google Public Location Badge for Google Latitude users. The badge lets you share your Google Latitude location publicly on a blog or web site.
To embed a map of your location on your website or blog you can just cut and paste a few lines of embed code. Or, for the more adventurous, you can use a KML or JSON feed to create your own custom application
Google Talk Location Status
Google are also now allowing Google Talk or Gmail chat users to share their Google Latitude location. If you enable the new feature in Google Talk then your location will be automatically updated with the name of the city that you are in.
