My son, Yashamaru, had a birthday the beginning of this month. On that day he was up most of the night finishing up the code of a program he wrote for the PSP. That was not unusual, he does that a lot. What I found interesting was that he wanted to get it out to give to the world, as a birthday gift from him to all of US.
There are a lot of important things that come about because of Open Source. But I feel the "mind-set" of sharing is very close to the top of the list.
