OK but you're talking about the brilliance of the Facebook concept and making it happen. Now it's out there with all its good points and plenty of not so great issues, and now he's already cashed out some of the billions he's made. You could ask how much skin he really feels he has in this game, in the sense of how much can you care about the next zillion billion. Others, big investors, will be looking harder at the wisdom of this particular acquisition. If you have millions of FB shares in some fund that you manage, then it's likely you are not exactly thrilled this evening.
Hence my point. He's a smart man. And an extremely rich one. And no one here knows how this latest acquisition will pan out.

That assumes that what they do is unique, the fact that they now needed to buy another company with almost as many daily users as Facebook is proof that what they do is not unique. Internet and it's different protocols are by their very nature 'social', which is why we see these platforms come and go.
Google became a giant, it would be difficult to knock them off their throne. Other companies do advertising too. Currently the same holds true for Facebook. I'm sure that they will fade away, maybe sooner than later. But to call a young man who made a mult billion dollar empire out of chatting with his fellow students an idiot is comical.
