Zuckerberg says that this is in fact a return to the company’s roots. “When I first made Facebook, we actually offered some functionality that was like this but only for your college,” he says. “Facebook then was arguably as much for meeting new people around you and exploring your community as it was for keeping in touch with the people you already knew. But it was such a hard problem to do it for more than a few thousand people at a time. We transitioned from connecting with whoever you wanted to primarily staying with people you already knew. But Graph Search is like the grown-up version of that discovery aspect. Exploring your community is a core human need, and this is the first big step we’re taking in that direction.”
