New Facebook changes to allow users to get more conrol when sharing and to own their own data.

Last week, Facebook unveiled some changes to its site in the hope of making it more accommodating to its millions of users. In a nutshell, the changes are meant to give users more control over the personal information they share on the site with different categories of people. For that purpose, Facebook has come up with the idea of allowing its users to divide their "friends" into different groups that can be public or private and differenciated by the depht of what can be shared with them.
Another issue addressed by the changes, is one that has raised a lot of questions in the past:data control. Critics have long blasted the social network giant over who can access users' data and what they can do with it. Facebook has taken the steps toward satisfying those critics thanks to two new features.
The first "one is a dashboard feature that allows users to keep track of information-sharing settings from third-party apps, such as plug-ins to other websites" according to the Wall Street Journal. Also, the dashboard displays exactly what personal information the apps of users' friends are pulling from them.
The other criticism leveled towards Facebook has always been about its take on data ownership. With the new changes, Facebook appeared to adopt a new attitude towards the issue.
The other new feature allows people to export the information they have entered into Facebook into one compressed zip file. With the information download feature, users become owners of their own data files, and could take them to other services the Wall Street added.
