Facebook is probably more than the deepest, broadest and the most comprehensive data set of human statistics ever collected compared to any other social media network sites. Google probably has more, but the information collected by the search engine is a little less personal.
In every occasion people login to Facebook, statistics are collected from every user of either the site or the app. Clicking on news feeds, a photo "like" or even messages or comments people send and share using this social media platform, a small portion of a person's individuality is being collected and processed through its vast universe of facts and figures.
On the other hand, search engines like Google probably has more than Facebook with regard to web searches and the Google app on iOS and Android devices -- although it would seem that this kind of information collected is less intimate. Data collected by the social network site has been turned to advertisements based on user information, which could be very annoying at times as it keeps on popping up and about as people use the site or app, and also quite often irrelevant as it has nothing to do with what people are doing.
The interesting part of the social media site collecting such data is that how it interpolates or presumes a person's behavior. In other words, it can predict a person by their liking and sharing news feeds or commercials, or reacting to certain news and information.
For a more thought-provoking part, Facebook with all its collective data of a person could describe him or her best than he or she could. It could be a pretty abstract as people personally give away such very personal information to the social networking site and gives it the capacity to describe its user quite accurately. Nowadays, algorithms are being initiated for character judgement. It can also determine if people's relationships are in troubled water based on collective social graphs.
As of the moment, Facebook is keeping on expanding with its billions of users worldwide and still collecting personal data as time flies by. Although it does not clear the smoke as if it will be used to describe an individual's personality, it might just be its way of making money out of its users as a dense way of using all of its gathered information.
