I'm not sure 4 is in the right order, considering you didn't name anyone/anything. I would put kernel dev's above framework devs. 0 and 1 are equal in my mind. Basically you should be able to give names for up to your #8 if you can't name person/company/project it should probably be lower.
I would order 0 1 (etc), 2, 3, 5, 8, 4, 7, 9, 10 11, 12, 13, 14 (comma placement is explicit where I find those levels equivalent)
Yeah, I was thinking kernel dev's would be the people who work on operating systems in #4. I didn't say "Linux devs" because I didn't want to include people who wrote some weird GTK/KDE apps used by one person to be included.
But kernel dev's would have been better terminology.
Tim Berners-Lee is maybe 3, or maybe category for people who "got lucky once and are now famous". Or maybe there should a separate category called "semantic web specialists". That may or may not be the same category as "Don Quixote, and other windmill tilters"
