It’s the ongoing debate of algorithms versus friends:
Imagine, for example, if online comments were written by people using their real names rather than by anonymous trolls. “Up until now all the advancements in technology have said information and data are the most important thing,” says Dave Morin, Facebook’s senior platform manager. “The most important thing to us is that there is a person sitting behind that keyboard. We think the Internet is about people.”
Having actual people, ones that you listen to, shape what you search for and what ads you’ll see is a powerful idea. People who you know can give better recommendations than some company — you trust them and they understand you.
