Another is about making something people want.
There are less people uses Sparc, Solaris, Java than people wants a "platform" to write applet that let you water plants.
(How many people has to use java, sparc, solaris? less than 10 million globally, How many people has to use facebook to check their friends? 100 millon+)
The world is cruel. You can put your heart and soul in inventing some cool stuffs that worked behind tables and only few appreciate them. So if we wants to do cool stuffs, you have to forget claps from the audience.
