To whoever collects evidence -
I admit to have met Quinn face-to-face SEVERAL times, in 4 or 5 different WWDC occasions, from about 1995 to (I'm not sure here) 2010. I also know his name from header files of the late OpenTransport technology and even the larger-scale "Power" set of communications/networking technologies that Apple brewed in the last 5 years of MacOS classic (7,8,9).
This means, I can remember his face, with no direct connection to any developer support incident. Rather a beer (or was it white-wine?) in one of the WWDC receptions in San Jose, CA.
I even owe him my life and happiness - as one of his indispensable comments in one of Apple's old header files, said "Don't do XXXXX or you will never have a happy life". Fortunately I read this note in time to see my code contained exactly XXXXX - so I found another way of doing what I needed, and my life was saved.
