The top-ten list needs Galileo. Galileo > Newton. Galileo > Einstein.

And Berners-Lee? If he had never started the WWW, within 2 years of when he did start it, someone else would have started something very similar. (And his W3C does dumb things.) If you want a contributor to the internet on the list, I humbly suggest J.C.R. Licklider, his protogee Roberts, or one of the four authors of "The End-to-end Argument".
