Mark Zuckerberg explains why he just changed Facebook's mission money.cnn.com

Mark Zuckerberg has spent the last dozen years making sure you know what your friends' babies look like and what your high school friends think about politics.
And, of course, transforming media and politics by presenting news and opinion — true and fake — to billions of people around the world.
Now the Facebook CEO is acknowledging that connecting people online isn't enough.
"We used to have a sense that if we could just do those things, then that would make a lot of the things in the world better by themselves," Zuckerberg told CNN Tech. "But now we realize that we need to do more too. It's important to give people a voice, to get a diversity of opinions out there, but on top of that, you also need to do this work of building common ground so that way we can all move forward together."
