Zuckerberg beats around the bush, obviously trying to avoid any connection to data security / privacy. ‘We – Facebook – offer you the option to mingle with your ‘friends’ but reserve the means you can do this, but now we offer you to put your data into various contexts.’
We’ve long heard that people would find Facebook more useful if it were easier to connect with smaller groups of their friends instead of always sharing with everyone they know.
This actually means that now you can decide who can see / interact with your data, but still Facebook does not give any insight what happens with data you think you delete from your profile. As now you will be able to
download to your computer everything you’ve ever posted on Facebook and all your correspondences with friends: your messages, Wall posts, photos, status updates and profile information.
I thought I deleted this already? So why can I download it now?
As at the very end of the post, Zuckerberg says ‘You can change the settings for an application to make less information available to it, or you can even remove it completely.’
