I always felt that Tim Berners-Lee was not respected enough in both the computer science and programming communities. I felt it especially after working for over a decade at Google, which literally built its entire business on TBL's architectural concepts. For example, Google and other search engines would not work without the principle of least power [1], which a lot of people, including Alan Kay [2], somehow don't…
I don't want to detract from TBL's accomplishments, especially on this occasion but, he didn't solve the hypertext problem insomuch as he decided that the really hard things like provenance and bidirectional linkages weren't important. Google and Facebook did solve those problems, but only for commercial benefit. Moreover, it's clear that TBL regrets that early decision to the degree that he rails against the walled…
