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)
