With the apparent backdrop of the argument that constant changes made by social networks like Facebook result in a substantial amount of sharing of users’ profile data with third-party websites, two non-profit groups - the Electronic Frontier Foundation (EFF) and the liberal activist group MoveOn. org – have attacked Facebook’s privacy policies.

Raising concerns about the most recent privacy policy update by social network Facebook, four US senators - Charles Schumer, Michael Bennet, Al Franken, and Mark Begich – have written an open letter to the company, objecting to its sharing of users’ personal information with other websites without prior consent of the users.

A website has been discovered by Verisign's iDefense Labs that has about 1.5 million compromised Facebook accounts "for sale". They are available at a selling price of $25 per 1000 accounts with ten friends or less and $45 per 1,000 for those accounts who have more than ten friends.

At its recent F8 developers’ conference, popular social network Facebook unveiled a number of new features that are aimed at facilitating the users in building their Facebook profile as well as in sharing online articles and other items with their friends.

With Facebook Wednesday unveiling a series of new development tools – which will essentially mark the “Like” button’s omnipresence on the Web and supposedly facilitate a seamless, semantically-enabled Web of human relationships -, it is evident that the social networking phenomenon is looking to extend its reach across a bigger span of the Web.

The Facebook F8 conference on Wednesday witnessed the official launch of Docs. com, also called Docs for Facebook - a new online app developed by Microsoft’s FUSE Labs; giving users the ability to create, edit, and share Microsoft Office documents with their Facebook friends.
