So how predictable can Reddit's users  be these days? In advance of his turn at Reddit's Ask Me Anything  put out a video with some of the questions he expected to be asked during his Q&A session. They included: How much money is in your wallet? (short answer: $100);  (short answer: if you are a poor farmer or a child growing up without access to life-saving vaccines you can have some money, otherwise no); Which would you rather fight--100 duck-sized horses or one horse-sized duck?
