I made sure to donate for the sheer fact that it will change this kid's life to see his dream come to fruition. His story alone has hit the media and will be sure to inspire god knows how many other young children.
Funny, I had exactly the same impulse. When I saw the kid as a proto-hacker, I came to the realization that we have to encourage such behavior. Would be awesome if everyone on HN gave at least the equivalent of a Superpass ($2) and I suspect we'll not only see this kid hanging out around here soon but I also wouldn't be surprised if we see him posting cool projects too :)
