Google Latitude just released a couple of new tools:
Google Public Location Badge is the first one.
With this tool you can add a badge to your blog or website that will let your visitors see where you are. You can set the level on the nearest location, or you can set the location to city level. It basically tells people where you are when you are signed in to your Google account. Read more here.
The other one is the Google Talk Location Status (beta).
This one works with Google Talk (and Google Talk in Gmail). It will change your status to your current location. Read more here.
Both of these new options need to be enabled in order to use them. The links that I have included in this blog will take you to the correct spots to enable. Of course, you will also need a Google Account.
