Very interesting discussion.

One gem: "So the way I hope that it will work for the Web protocols and the WWW standards which I hope will be able to evolve from their kludgy current state towards that beautiful golden dream is that in any case where you lay down a standard, you also allow there to a second and you show a path whereby is a third one comes up that is better you can move in that direction on the heels of the first, keeping it honest and you have a hook in it to be able to hook it all together later on." (Tim Berners-Lee)
