One of the smartest people I've encountered, even if it is only on Quora. Great sense of humor, doesn't pretend to have answers on things he doesn't know about

One of the smartest people I've encountered, even if it is only on Quora. Great sense of humor, doesn't pretend to have answers on things he doesn't know about. Probably a great guy to work with and for. Congrats, Yishan.
