Is Facebook reading your unpublished mind?

Do you know that Face book saves the status, chat, comment that you type but do not post.

Yes, it is true. In a press release Facebook team revealed that they collects the data about what you do not do.

Adam Keamer, data scientist of Facebook and his intern collected data like this randomle of five million users in July for study.

Facebook team reveled that they collected these data from HTML form element and not from keystrokes.They also collected demographic data.

How it works?

 For simplicity it works like Gmails draft. The mails you write it keep on automatically saving in your draft box and you can see the approx full mail even if you don't save and close the mail composing window
