Had it been early years of YC, this post of explaining herself could have made sense. After so many years of being at the helm of YC, who is a nut to doubt her? Or is it that she is still insecure and any indirect reference to her capability, she begins to explain herself. I am speculating and I would be really happy to be proven wrong!
