The world's largest social networking site, Facebook, has decided to rid itself of regional networks like India and China in a bid to tighten its privacy policy. Following this move, thousands of Facebook users from India, who had opted for the "India" network when joining the social networking site, will have to revise their settings.

Every Indian who joins Facebook has an option to choose the "India" network. India has nearly 12 million Facebook users, and the number is growing steadily. And there are numerous "India networks" -- the largest have around 13,198 members. Compared to this, Orkut (owned by Google) has around 16 million users, but the numbers are declining.

Since this update will remove regional networks and create some new settings, in the next couple of weeks Facebook will ask its users to review and update their privacy settings. Users will see a message that will explain the changes and take them to a page where they can update their settings. When they're finished, it will show a confirmation page so that one can make sure one has chosen the right settings. As always, once the task is done, users will still be able to change the settings whenever they want.

Facebook has its reasons. Almost 50 per cent of all the 350 million-odd Facebook's active users are members of regional networks, "so this is an important issue for us", said Facebook Founder Mark Zuckerberg in an open letter to users.

"The positive side is that users will be better able to protect their privacy. On the negative side, users like me who have hundreds of contacts who have added me as friends, would now have to sift through those lists and decide who should see what. This is going to be very painful. It will need a software to manage these third-party contacts," rues Mahesh Murthy, founder and cheif executive officer of search engine marketing firm, Pinstorm.
