The International Herald Tribune has a good article on the award, with quotes from Berners-Lee. My favourite:
The problem now is someone can write something out of their own creativity, and a lawyer can look over their shoulder later and say, 'Actually, I'm sorry, but lines 35 to 42 we own, even though you wrote it.' What's at stake here is the whole spirit in which software has been developed to date. If you can imagine a computer doing it, then you can write a computer program to do it. That spirit has been behind so many wonderful developments. And when you connect that to the spirit of the Internet, the spirit of openness and sharing, it's terribly stifling to creativity. It's stifling to the academic side of doing research and thinking up new ideas, it's stifling to the new industry and the new enterprises that come out of that.
Hurray for freedom of thought, speech, good ideas, and software!
