I tried to write a Tl;Dr for this - i don't think I can. It seems to be good start up ideas exist in the 'one step removed' phase space of all possible startups - not so far advanced that you need to teach Henry Ford about computers, but just one extra 'twist'. This seems to be however leading to startups should iterate through 'Facebook but for [dogs,cats,fish,mobile phones]" which I am not sure wins. But I loved the history of Godel etc.
