Facebook has undergone further scrutiny following its latest updates, including the anticipated \'Timeline\' feature.

The most recent update last week, sparked fury from most of its users, some of which posted chain letters on the social networking site in protest.

Now, future features that are only available in the developer\'s release -which can be accessed quite easily- are being slammed over privacy issues.

Timeline starts by showing photos of the user in chronological order, it also shows historical status updates, movies watched on Netflix, music listened to on spotifty and 4square check ins.

The changes prompted a Wall Street Journal poll which showed 84% of users were unhappy with Timeline.

The new feature will be available to the wider public in the coming weeks, with many people dreading the new feature.

David Meyer, who is trying out the new system said, \"Until now, Facebook has allowed a certain amount of obscurity for older content, but that is no longer the case. It\'s all out there now, and it\'s easy to find. All that\'s missing is semantic search, but I\'m sure Zuckerberg is already working on that.\"

Cornish marketing strategist and social media guru, Aren Grimshaw reacted positively to the updates saying: \"The new Facebook Timeline redefines the role Facebook plays in our lives. No more is it just a place to share our experiences with friends and family, it has the potential to become an invaluable resource for creating and accessing our own life story. \"

\"There will be those who get caught out by the sudden return of their previous updates, re-sharing details that seemed fine to share at the time of posting; however, a quick scan of the privacy settings can easily avoid any embarrassment. \"

\"As someone who had become a little bored by Facebook, I personally think the changes make the site relevant and personal again.\"
