Zuckerberg summed up the achievement with a link to the video embedded above and a long string of metaphors:

Facebook isn’t the first thing people have made to help us connect. We belong to a rich tradition of people making things that bring us together. Today, we honor this tradition. We honor the humanity of the people we serve. We honor the everyday things people have always made to bring us together: Chairs, doorbells, airplanes, bridges, games. These are all things that connect us. And now Facebook is a part of this tradition of things that connect us too.
