I like the human story: Stewart Butterfield co-creates Flickr, revolutionizing online photo sharing; sells it for what at the time was "real money" but quickly discovers he could have held out for a whole lot more; burns through some VC failing at games; and then has that Eureka! moment when he realizes the Enterprise will eat any damn thing you feed it, and he hatches his plan to join the nine-zeroes club he missed out on in 2005, software quality be damned!
