Google Mobile Maps feature called Google Latitude is released thru which you can publish your location to your selected friends and family. The new feature lets you broadcast your current location to a select few people based on where on the GPS from your mobile phone.
Blackberry, Windows Mobile and Nokia S60 users can access it very shortly via Google.com/latitude on their phone. Here iPhone users will have to wait for another release.
If you don’t have smartphones, just don’t worry. Visit google.com/latitude on your desktop or laptop to install the Latitude iGoogle gadget and share your location right from your computer. If you have Google Gears installed in your browser (you do by default if you use Google Chrome), you can automatically share your location; otherwise, manually set your location to let your friends know where you are.
Older social networks such as Loopt, Whrrl and Brightkite all of which are doing their best to become the best mobile social network, but Google will now break their dreams as well because Google’s market foothold is really large.
