"Paul Graham ... is making a large amount of very small investments each with an extremely risky yet potentially huge return."<p>Based on the success rates so far, why do people still consider pg's bets to be risky? Do people still think he sends a shoebox full of $10K to kids in their dorms and then checks back in 3 months?<p>Is it in YC's interest to make knowledge of it's success rate more well known or more private? Since pg has discussed it somewhat in the open, I'm assuming the former.
