My first thought after reading the beginnings of his bulleted list: PHP? Haha. Still reading. It feels almost surreal to be reading the brain dump // stream of consciousness of someone who's created something so great. He talks just like you or I. Very fascinating.
There's nothing special about getting something like that done. There's nothing special about people who spend time on that kind of stuff either, save for the fact that they spend time on it. It's not difficult to be at the top, what's difficult is getting there and having enough resolve and persistence to do it. Only change is painful.
