>    Facebook's draw is its ability to give you what you want. Like
>    a page, get more of that page's posts; like a story, get more
>    stories like that; interact with a person, get more of their
>    updates. The way Facebook determines the ranking of the News
>    Feed is the probability that you'll like, comment on, or share
>    a story. Shares are worth more than comments, which are both
>    worth more than likes, but in all cases, the more likely you
>    are to interact with a post, the higher up it will show in
>    your News Feed. Two thousand kinds of data (or "features" in
>    the industry parlance) get smelted in Facebook's
>    machine-learning system to make those predictions.
