Mark Zuckerberg, left Facebook today.

It's confirmed by her verified Twitter-account, with a tweet of herself.
So, no more Randi there, but there are stil 749.999.999 million people left. And probably, if you read the end of this article, we might have a few thousands more. Or not, if they all move to Google+ now :)
