With an internal Justice Department document, recently obtained by the Electronic Frontier Foundation (EFF), having revealed that US law enforcement agents have collecting data on social networking sites like Facebook for fighting crime, Internet security professionals have shared their apprehensions with eWEEK.

According to the most recent information revealed by online measurement service Hitwise, Facebook has toppled Google to become ‘the most visited site of the week’ in the US – a ranking that Google had consistently been holding since 2007. The last time that Google missed the most popular site slot was in September 2007, when it was overthrown by MySpace.

The Pentagon announced on Friday to have authorized the use of about 10 social-networking sites such as Twitter, Facebook and other so-called "Web 2.0" sites across the U. S. military, posting that the benefits of social media outweighed security concerns.

Facebook is once again in troubled waters over its security concerns as it inadvertently routed e-mails to the wrong addresses.

The engineers diagnosed the problems moments after it began and immediately resolved it. However, because of the glitch, the affected users were unable to access their accounts.

After heady, early days, full of chaos on the Internet, the situation has settled down into a stable middle age with password protection, tagged photos and user-friendly interfaces. However, Chatroulette has emerged as a silence breaker.

For all constant users of LinkedIn, Facebook and other social networking websites, who use these as a tool for managing their business contacts, the latest update that is being provided by Microsoft to Outlook, announced last week, will come as a boon.
