Last month google introduced a new feature called Google Latitude, which is a feature of Google Maps for Mobile that lets you (if you choose to opt-in) share your whereabouts and receive updates about your friends' approximate locations. Google today announced this feature availability in Orkut. They have created a Google Latitude application.
With this app, you can share your location and see your friends' locations on a map inside of orkut. Notice that an old friend is back in your hometown? Just click on her photo and send a scrap or head to her profile page and see what she's up to.
If you use Google Latitude from your mobile phone, you can even send your friends updates on your location while you're out and about, making it easier to bump into the people you care about.
You have control over what and when you share and who you share it with. You can go through Latitude's privacy features. Watch below video for more details.
