As an experiment, I hit the like button on the pages of a few Republican politicians and all of a sudden I found myself in a very different part of Facebook than I was used to.
The News Feed is a tool for consuming not just news stories and memes that interest you, but also those that your friends like. Few people — if anyone — use Facebook the way I have. Your friends interests and tastes have a tremendous effect on what you see. But I wanted to see how Facebooks recommendation algorithms worked in a purely friendless vacuum. What kind of content would it suggest if all it had to go on was what I liked, rather than who?
