That's really a great example against the Dropout myth. Shows that's it success is more random than many thinks.

I think there's a great lesson here: It takes only 2 years and 13 people to overtake one of Facebook core features. And that's talking about a company that suppose to have the best programmers and designers in the world. That's something you should remember next time someone's tells you that Facebook/Google/Microsoft will do it better.
